Also modified zprocess routines to use Launch(). +</ul> + +<H2> Public Release 1.4.0 (15 August 2007)</H2> + +<ul> +<li> Public release of production-quality code, incorporating changes +and improvements from previous beta releases, including: +<ul> +<li> Support for access to ASCII text column files. +<li> Support for fast indexed access of binary tables. +<li> Support for database views of tables, i.e. pre-set values for the filter + specification, the columns to activate, and display format. +<li> New programs include funcone (cone search), funindex (create index files), + and funcen (calculate centroids within regions). +</ul> + +</ul> + +<H2> Release 1.3.0b[n] (mainly internal SAO beta releases)</H2> +<ul> + +<p> +<li> Added -F[c] switch to change the column delimiter to the +specified character. + +<p> +<li> Extended fundisp's format switch (-f) so that it can now handle complex +formats such as 'x=sometext%3d- y=othertest%3d.ext'. + +<p> +<li> Added support for creating and processing 1D FITS images. + +<p> +<li> Added vcol=colname and vcol=/colname to filter specifications to +support use of a third value column when binning 2D images. + +<p> +<li> Added switches to funcone to write out data rows are not within +any cone (-J, -X) and centers which have no close data rows (-L). + +<p> +<li> In funjoin, added ability to specify a numeric tolerance for when joining +two files. + +<p> +<li> shared memory support in gio now can create a shared segment if w+ is +specified as the open mode. + +<p> +<li> Changed reggeometry man page so that examples correctly show angles +going counter-clockwise from the x-axis instead of from the y-axis. + +<p> +<li> Added checks to funmerge to ensure that all files have the same columns. + +<p> +<li> Fixed bug in text support that prevented header-less files from being +processed properly. + +<p> +<li> Added support for 64-bit images (bitpix=64) and table columns (TFORM=K). + +<p> +<li> Filter code was not applying bscale/bzero to columns. + +<p> +<li> Fixed funimage bug that caused a .5/block error in WCS CRPIX values +generated from binary tables. + +<p> +<li> Added feq(a,b) and div(a,b) macros to funcalc. + +<p> +<li> Added support for single-line #define to funcalc. + +<p> +<li> Updated wcs library to 3.6.6 + +<p> +<li> Fix bug in funcen in which ra,dec was not being calculated correctly +if physical and image coords did not match up. + +<p> +<li> The filter syntax "col1 = col2" now explicitly generates an error +(you really want to do "col1 == col2"). + +<p> +<li> Added -o switch to include offset from the nominal target position. + +<p> +<li> Fundisp now displays multi-dimensional vector columns properly. + +<p> +<li> Documented support for lists of files processed as a single file +using "list: file1 ... filen" syntax. + +<p> +<li> Fixed bugs in support for pipe file type (i.e. ability to pass +commands as a filename using "pipe: cmd arg1 ... argn" syntax). + +<p> +<li> Fixed bug in funhist processing of image-based pixel histograms +(i.e using "xy" for columns) where a region was specified. All pixels +outside the region were erroneously being added to the bin containing +the 0 value. + +<p> +<li> Disabled multi-file processing in funds9, which was breaking support +for pathnames containing spaces and is not used by ds9 anyway. + +<p> +<li> Added support for Views of tables, i.e. pre-set values for the +filter specification, the columns to activate, and display format +(though the latter is for fundisp only). + +<p> +<li> Added -l switch to funimage to read x, y, val columns from a list. + +<p> +<li> Removed useless and meaningless section syntax foo'[*]' because it +breaks pointer de-referencing on string columns (i.e. foo'[*xxx=='a']'). +Use foo'[*,*]' instead, as documented. + +<p> +<li> String variables were not always being terminated properly in the +filter code because FITS 'A' data is not necessarily null-terminated. + +<p> +<li> Added funtools version number to all usage() displays. + +<p> +<li> Added explanation of switch arguments to many usage() displays. + +<p> +<li> The filter keyword row# now supports single row selection as well +as range selection, i.e., "row#=100" along with previous "row#=100:200". + +<p> +<li> fundisp now outputs "0x" before hex values. + +<p> +<li> Fixed bug in filter parser which processed rangelists incorrectly +if spaces were put into the rangelist (i.e. "pha= 1 : 3" instead of +pha=1:3). + +<p> +<li> Fixed a bug in funindex which created a wrongly named index file +if more than one "." was in the input file name. + +<p> +<li> Added support to funcone to take ra, dec, radius from a list +(i.e. columns in a FITS file or a text file). + +<p> +<li> Fixed a bug in FunColumnActivate so that if some columns are +explicitly activated while others are de-activated, only the +explicitly activated columns are activated (code was activating all +columns in this case). + +<p> +<li> Fixed a bug in funindex which prevented indexing tables containing +a column named N. + +<p> +<li> fundisp now encloses ASCII column values in single quotes (unless +-T is specified to output RDB format). + +<p> +<li> If a filter specification only involves indexed columns, then the +compiled filter is not used. + +<p> +<li> Funmerge can now be given a list of files to merge using @list syntax. +Also removed the restriction on how many files can be merged (was limited to +the max number of open files). + +<p> +<li> Added ability to edit (add, delete, modify) header parameters in funhead +by specifying an output file (editing acts as a filter) and an edit command +file (which can be stdin). + +<p> +<li> Funtools now contains preliminary code to support (fast) indexed access +of binary tables. See idx.html or "man funidx" for more details. + +<p> +<li> Funtools now contains preliminary code supporting access to ASCII +column files. See text.html or "man funtext" for more details. + +<p> +<li> Fixed bug in funcalc in which columns used in an expression were +always being replaced by new columns, with all associated parameters +(e.g. WCS) were being deleted. Now this only happens if the column +explicitly changes its data type. + +<p> +<li> Fixed bug in funcalc in which the raw data and user data became out +of sync for one row after every 8192 (FUN_MAXROW) rows. + +<p> +<li> Fixed bug in gio in which gseek returned 0 instead of the current byte +offset for disk files. + +<p> +<li> Added funcone program to perform cone search on RA, Dec columns in +a FITS binary table. + +<p> +<li> Fixed bug in polygon, pie and rotated box region filtering for +tables (nearby rows exactly in line between two non-vertical or +non-horizontal vertices were being accepted incorrectly). + +<p> +<li> Fixed pie and panda regions so that the angles now start from +positive x axis == 0 degrees and run counter-clockwise, as +documented. They were going from positive y. NB: a similar change +was made to ds9 release 4.0b3. You must be using ds9 4.0b3 or later +in order to have the correct behavior when generating regions in ds9 +and using them in funtools. + +<p> +<li> Added -p [prog] switch to funcalc to save the generated program. +instead of executing (and deleting) it. + +<p> +<li> Upgraded zlib to 1.2.3. + +</ul> + +<H2> Patch Release 1.2.4 (internal SAO and beta release only)</H2> +<ul> + +<p> +<li> In funcalc, added support for user-specified arguments via the +-a [argstr] switch. These arguments are accessed in the compiled program +using the supplied ARGC and ARGV(n) macros. + +<p> +<li> Added -n (no header display) to fundisp to skip outputting header. + +<p> +<li> Added checks for various types of blank filters. + +<p> +<li> Added macros NROW (current row number) and WRITE_ROW (write current +row to disk) to funcalc. + +<p> +<li> funcalc no longer requires that at least one data column be +specified in the compiled expression. + +<p> +<li> Added FUN_NROWS to FunInfoGet() to return the total number of rows in +an input table (i.e. value of NAXIS2). + +<p> +<li> The compiled funcalc program now includes stdlib.h and unistd.h. + +<p> +<li> The util/NaN.h header file is now modified at configure time to +contain endian status for the target architecture. References to +specific platforms have been removed. + +<P> +<li> Added -m switch to funtable to output multiple files, one for +each input region (and a separate file for events that pass the +filters but are not in any region). + +<p> +<li> Added ability to add new parameters (FunParamPutx) after writing +data if space is previously reserved in the form of a blank parameter +whose value is the name of the param to be updated. (Also requires the +append argument of FunParamPutx be set to 2). + +<p> +<li> Added ability to build shared libraries. With --enable-shared=yes, +shared library is built but not used. With --enable-shared=link, +shared library is linked against (requires proper installation and/or +use of LD_LIBRARY_PATH). + +<p> +<li> Added -v [column] support to funcnts so that counts in a table +can be accumulated using values from a specified column (instead of +the default case where an integral count is accumulated for each event +in a region). + +<p> +<li> Added funcen program to calculate centroids within regions +(binary tables only). Also added support for a funcen-based centroid +tool to funtools.ds9. + +<p> +<li> Fixed bug which prevented successful filtering of columns containing +arrays. + +<p> +<li> Added filter check to ensure that a column is not incorrectly used +as an array. + +<p> +<li> Fundisp now displays column arrays indexed from 0, not 1. + +<p> +<li> Added -i [interval] support to funcnts so that multiple intervals +can be processed in a single pass through the data. For example, +specifying -i "pha=1:5;pha=6:10;pha=11:15" will generate results in +each of 3 pha bands. + +<p> +<li> Fixed calculation of LTV quantities when binning floating point +column data (value was off by 0.5). + +<p> +<li> Added support for 'D' in floating point header values. + +<p> +<li> Added -a switch to funimage and funtable to append output image or +table to an existing FITS file (as an IMAGE or BINTABLE extension). + +<p> +<li> Added support for column scaling (TSCAL and TZERO) on input columns. +Note that the default column type is changed to accommodate scaling (e.g. +a column of type 'I' is changed to 'J', 'J' is changed to 'D') so that +the scaled values can be handled properly by programs such as fundisp +(which utilize default types). + +<p> +<li> Added support to FunColumnSelect() for handling structs of arrays +(i.e. where returned columns are contiguous) instead of the default array +of structs (returned row are contiguous). This is done by specifying +"org=structofarrays" in the plist and passing a single struct containing +the arrays. + +<p> +<li> When writing an rdb/starbase file, fundisp now outputs the full +column name, regardless of the width of the column (which ordinarily +is truncated to match). + +<p> +<li> Fixed support for large files by changing all file positions variables +from "long" declarations to "off_t. + +<p> +<li> Fixed bug in funcalc incorrectly processed multiple array +references (e.g. cur->foo[0]=cur->x;cur->foo[1]=cur->y;) within a single +line of code. + +<p> +<li> Added FILTER_CFLAGS environment variable for all filtering. Also added +--with-filter-cc and --with-filter-cflags options on configure to allow +specification of a default C compiler and associated CFLAGS for filtering. +All of this is necessary in order to support 64-bit libraries under Solaris. + +<p> +<li> Added the funtbl script to extract a table from Funtools ASCII output. + +<p> +<li> Added code to funimage to update IRAF DATASEC keyword. + +<p> +<li> Added checks to ensure that image dimensions are positive. + +<p> +<li> Fixed a bug in funimage where int data was being scaled using BSCALE and +BZERO but these keywords also were being retained in the output image header. +Now the data are not scaled unless the output data type is float (in which +case the scaling parameters are removed). + +<p> +<li> Fixed a bug in funmerge which prevented merging of files unless one of +the -f, -w, or -x switches were used. + +<p> +<li> Fixed a bug in funtable and fundisp which caused the special '$n' column +to be output incorrectly. + +<p> +<li> Fixed sort option in funtable, which previously worked only if the +record size was an even divisor of 8192 (and returned garbage otherwise). + +<p> +<li> Fixed bug in filters involving FITS data type 'X' (bitfield). + +<p> +<li> Fixed bug in funcnts in which the output angles and radii were +being displayed incorrectly when multiple panda shapes were specified. + +<p> +<li> Fixed bug in pandas and pies using n= syntax when first angle +specified was greater than second. The resulting mask was of +the correct shape but contained only a single region. + +<p> +<li> Table row access routines will now decrease maxrows if memory cannot be +allocated for maxrows*sizeof(row), i.e. if the size of a row is so large that +space for maxrows cannot be allocated. + +<p> +<li> The FUN_MAXBUFSIZE environment variable was added to limit the +max buffer size that will be allocated to hold table row data. The +default is 5Mb. + +<p> +<li> Generated PostScript and PDF versions of the help pages. + +<p> +<li> Moved OPTIONS section before (often-lengthy) DESCRIPTION section in +man pages. + +<p> +<li> All memory allocation now does error checking on the result +(except wcs library, which is external code). + +<p> +<li> Removed some compiler warnings that surfaced when using gcc -O2. + +<p> +<li> Updated wcs library to 3.5.5. + +<p> +<li> Upgraded zlib to 1.2.1. + +</ul> + +<H2> Patch Release 1.2.3 (12 January 2004)</H2> +<ul> + +<p> +<li> Generated man pages from the html pages. These are installed +automatically at build time. + +<p> +<li> Changed instances of sprintf() to snprintf() to protect +against buffer overflow. + +<p> +<li> Fixed a number of compiler warnings in non-ANSI compilers. + +<p> +<li> Increased SZ_LINE parameter value from 1024 to 4096. + +</ul> + +<H2> Patch Release 1.2.3b1 (19 August 2003)</H2> +<ul> + +<p> +<li> The rule for using comma to separate a table filter expression +and a region expression has been changed. The rule now states: +<ul> +<LI> if both expressions contain a region, the operator used is <B>or</B>. +<LI> if one (or both) expression(s) does not contain a region, the operator +used is <B>and</B>. +</ul> +This rule handles the cases of pure regions and pure column filters properly. +It unambiguously assigns the boolean <B>and</B> to all mixed cases. Thus: +<PRE> + foo.fits[circle(10,10,3),pi=1:5] +</PRE> +and +<PRE> + foo.fits[pi=1:5,circle(10,10,3)] +</PRE> +both are equivalent to: +<PRE> + foo.fits[circle(10,10,3) && pi=1:5] +</PRE> + +<p> +<li> When include files are used in filters, they now have implied +parentheses surrounding them. Thus, if a region file foo.reg contains two +regions (e.g. circle 1 2 3 and circle 4 5 6), the syntax: +<pre> + pha=4:5&&@foo.reg +</pre> +is equivalent to: +<pre> + pha=4:5 && (circle 1 2 3 || cir 4 5 6) +</pre> +instead of: +<pre> + pha=4:5 && circle 1 2 3 || cir 4 5 6 +</pre> +and the pha filter is applied to both regions. + +<p> +<li> Filters and comments now can be terminated with the string +literal "\n" as well as ";" and the new-line character. This means +that a region can have comments embedded in it: +<pre> + funcnts foo.fits "circle 512 512 10 # color=red\n circle 512 512 20" +</pre> + +<p> +<li> Added capability to update the value of an existing parameter +after writing the table or image (assuming the output image is a +disk file or is being redirected into a file). + +<p> +<li> Improved handling of parentheses in filter expressions. + +<p> +<li> Fixed a bug in image (not event) regions in which circles and +annuli with radius of 1 pixel were not being processed. No counts and +no area would be found in such regions. + +<p> +<li> Fixed a bug in funcnts in which the radii column values for out of sync +if multiple annuli were specified (instead of a single varargs or accel +annulus). + +<p> +<li> By default, fundisp will display integer image data as floats +if the BSCALE and BZERO header parameters are present. + +<p> +<li> Added -L switch to funhead to output starbase list format. + +<p> +<li> Changed the name of the routine _FunColumnSelect to +FunColumnSelectArr, in order to emphasize that it is not +a private routine. + +<p> +<li> Funcalc now checks to ensure that a column was specified as part of +the expression. + +<p> +<li> Funcalc local variables in the compiled program now use a "__" prefix +to avoid conflicts with user-defined variables. + +<p> +<li> Unofficial unsigned short (bitpix=-16) image data now is scaled +correctly using BSCALE and BZERO header parameters. + +<p> +<li> Ported to Intel icc and gcc 3.3 compilers. + +<p> +<li> Updated wcs library to 3.5.1. + +<p> +<li> Changed license from public domain to GNU GPL. + +</ul> + +<H2> Patch Release 1.2.2 (18 May 2003)</H2> +<ul> + +<p> +<li> Fixed funcalc so that it now actually compiles an expression and +runs it, instead of getting a "filter compilation error". Oops! + +<p> +<li> Fixed bug in FunOpen in which the bracket specification was being +removed from the filename if a disk file was opened for "w" or "a". + +<p> +<li> Fixed bug in FunFlush which prevented two successive calls to +FunImagePut from writing the second extension header properly. + +<p> +<li> All filter routines now use gerror(stderr, ...) call instead of +fprintf(stderr, ...) so that output to stderr can be turned off (via +setgerror(level) or GERROR environment variable). + +<p> +<li> All standard Funtools programs check for GERROR environment +variable before setting gerror flag. + +<p> +<li> Some error messages about invalid region arguments were not being +printed. + +<p> +<li> FITS parameters/headers now conform more closely to FITS standard: +<ul> +<li> Blank keywords are treated in the same way as COMMENTS and HISTORY cards +<li> XTENSION keywords are now exactly 8 characters long +<li> 'E' is output instead of 'e' in floating point param values +<li> PCOUNT and GCOUNT are output correctly for image extensions +<li> EXTEND=T is output in primary header +<li> COMMENTS and HISTORY start in column 9 +</ul> + +</ul> + +<H2> Patch Release 1.2.1 (24 April 2003)</H2> +<ul> + +<p> +<li> Varargs ellipse and box annular regions were being +processed incorrectly when the following conditions all were met: +<ul> +<li> the region was specified in physical or wcs coordinates +<li> the data file contained LTM/LTV keywords, i.e., it +was blocked with respect to the original data file +<li> the program being run was an image program (e.g. funcnts, funimage) +</ul> +Varargs ellipse and boxes are regions of the form: +<pre> + ellipse x y a1 b1 a2 b2 ... an bn [angle] + box x y l1 w1 l2 w2 ... ln wn [angle] +</pre> +where at least 2 sets of axis (length) values were specified to form +an annulus (i.e. simple ellipses and boxes worked properly). With all +of the above conditions met, a region in physical coordinates saw its +second length argument converted incorrectly from physical coordinates +to image coordinates. In simple terms, this means that funcnts did not +process elliptical or box regions in physical coords on blocked images +properly. Note that blocking on the command line (e.g. foo.fits[*,*,2]) +did work when no LTM/LTV keywords existed in the file. + +<p> +<li> The fundisp -f switch now supports specification of +column-specific display formats as well as a more convenient way to +specify datatype-specific display formats. Both use keyword=value +specifiers. For columns, use: +<pre> + fundisp -f "colname1=format1 colname2=format2 ..." ... +</pre> +e.g. +<pre> + fundisp -f "time=%13.2f pha=%3d" ... +</pre> +You also can specify display formats for individual datatypes using the FITS +binary table TFORM variables as the keywords: +<pre> + fundisp -f "D=double_format E=float_format J=int_format etc." +</pre> +e.g. +<pre> + fundisp -f "D=%13.2f I=%3d" ... +</pre> +The old position-dependent syntax is deprecated. + +<p> +<li> Fundisp will now print out a single 16-bit (or 32-bit) unsigned +int for a column whose data format is 16X (or 32X), instead of +printing 2 (or 4) unsigned chars. + +<p> +<li> Fixed bug in which fundisp was not able to display bitfield data for +raw event lists. + +<p> +<li> Previously, when binning columns used implicitly in a region +and explicitly in a filter could suffer from a case sensitivity problem. +This has been fixed. + +<p> +<li> Fixed internal mask=all switch on fundisp. + +<p> +<li> Filter include files now simply include text without changing the state +of the filter. They therefore can be used in expression. That is, if foo1 +contains "pi==1" and foo2 contains "pha==2" then the following expressions +are equivalent: +<pre> + "[@foo1&&@foo2]" is equivalent to "[pi==1&&pha==2]" + "[pha==1||@foo2]" is equivalent to "[pi==1||pha==2]" + "[@foo1,@foo2]" is equivalent to "[pi==1,pha==2]" +</pre> + +<p> +<li> Fixed bug in filter specification which caused a SEGV if a varargs-style +region was enclosed in parens. + +<p> +<li> Updated wcs library to 3.3.2. + +</ul> + +<H2> Public Release 1.2.0 (24 March 2003)</H2> +<ul> + +<p> +<li> BSCALE and BZERO are now always applied to int pixel data, instead of +only being applied if the desired output is floating point. + +</ul> + +<H2> Beta Release 1.2.b3 (4 February 2003)</H2> +<ul> + +<p> +<li> In FunColumnSelect, added the ability to specify an offset into +an array in the type specification, using the extended syntax: +<PRE> + [@][n]<type>[[poff]][:[tlmin[:tlmax[:binsiz]]]] +</PRE> +The [poff] string specifies the offset. For example, a type specification +such as "@I[2]" specifies the third (i.e., starting from 0) element in +the array pointed to by the pointer value. A value of "@2I[4]" specifies +the fifth and sixth values in the array. + +<p> +<li> Added a non-varargs version of FunColumnSelect called _FunColumnSelect: +<pre> +int _FunColumnSelect(Fun fun, int size, char *plist, + char **names, char **types, char **modes, int *offsets, + int nargs); +</pre> + +<p> +<li> Added support for sorting binary tables by column name using: +funtable -s "col1 col2 ... coln" ... + +<p> +<li> Added the FUN_RAW macro which, when applied to the "name" parameter +of FunParamGets(), returns the 80-character raw FITS card instead of +only the value. + +<p> +<li> Added support for comparing column values with binary masks of the +form 0b[01]+, e.g.: +<pre> + (status&0b111)==0b001 +</pre> +Previously, such masks had to be specified in decimal, octal, or hex. + +<p> +<li> Completed support for type 'L' (logical) in fundisp and in filtering of +binary tables. + +<p> +<li> Fixed bug in funhist that was improperly setting the number of bins +when the data was of type float. + +<p> +<li> Fixed bug in filter/Makefile where the filter OBJPATH #define was +being passed to the wrong module. + +</ul> + +<H2> Beta Release 1.2.b2 (7 October 2002)</H2> +<ul> + +<p> +<li> Updated wcs library to 3.1.3. + +<p> +<li> Added support for reading gzip'ed files via stdin. + +</ul> + +<H2> Beta Release 1.2.b1 (24 September 2002)</H2> +<ul> + +<p> +<li> Added the following accelerators to region filtering: +<pre> + shape: arguments: + ----- --------- + BOX xcenter ycenter xw1 yh1 xw2 yh2 ... xwn yhn (angle) + BOX xcenter ycenter xwlo yhin xwout yhhi n=[number] (angle) + CIRCLE xcenter ycenter r1 r2 ... rn # same as annulus + CIRCLE xcenter ycenter rinner router n=[number] # same as annulus + ELLIPSE xcenter ycenter xw1 yh1 xw2 yh2 ... xwn yhn (angle) + ELLIPSE xcenter ycenter xwlo yhin xwout yhhi n=[number] (angle) +</pre> + +<p> +<li> Added the following new pandas (Pie AND Annulus) to region filtering: +<pre> + shape: arguments: + ----- --------- + CPANDA xcen ycen ang1 ang2 nang irad orad nrad # same as panda + BPANDA xcen ycen ang1 ang2 nang ixlo iylo ixhi iyhi nrad (ang) # box + EPANDA xcen ycen ang1 ang2 nang ixlo iylo ixhi iyhi nrad (ang) # ellipse +</pre> + +<p> +<li> Added support for filtering images using simple FITS image masks, +i.e. 8-bit or 16-bit FITS images where the value of a pixel is the +region id number for that pixel (and therefore must be greater than +0). The image section being filtered must either be the same size as the +mask dimensions or else be an even multiple of the mask. This works with +image-style filtering, i.e., funcnts can utilize a mask on both +images and binary tables. + +<p> +<li> Added '$n' to fundisp column specification to allow display of +ordinal value of each row passing the filter. + +<p> +<li> Added code to support region filtering on image sections. + +<p> +<li> Fixed bugs which prevented filtering more than one ASCII region file. + +<p> +<li> Fixed bug occasionally causing filter slave processes to become zombies. + +<p> +<li> Fixed bugs in event filtering: annulus with inner radius of 0 +(i.e., a circle) was rejecting events with coordinates xcen, ycen. +Also, pie with angles of 0 and 360 was rejecting some events. +Image filtering (e.g. funcnts) did not have these problems. + +<p> +<li> Filters now accept global exclude regions without an include region. +In such a case, the field region is implied. That is, "-circle(x,y,r)" +is equivalent to "field; -circle(x,y,r)", etc. + +<p> +<li> Fixed panda so that it can be used as a global exclude. + +<p> +<li> Allow empty ds9 region file (comments and globals only) to be +a valid filter. Totally ignore zero length region or include file. + +<p> +<li> Fixed funcnts bug that was displaying 0 value as inner radius of +a circle, instead of just one radius value. + +</ul> + +<H2> Public Release 1.1.0 (22 April 2002)</H2> + +<p> +New features include: +<ul> +<p> +<li> Funtools programs now accept gzip'ed files as valid input. + +<p> +<li> Improved security via replacement of system() function. + +<p> +<li> fundisp, funcnts, funhist can output starbase/rdb format (tabs between columns, form-feeds between tables). + +<p> +<li> Improved support for Windows platform, as well as new support for Mac OSX. +</ul> + +<H2> Pre-Release 1.1.0e (10 April 2002)</H2> +<UL> + +<P> +<LI> Added enough support to skip over variable length arrays in BINTABLES. +We will add full support if this non-standard construct becomes more widely +used. + +<P> +<LI> Fixed bug in underlying fitsy _gread() routine that was returning +an arbitrary bytes-read value if the input fd was invalid. + +</UL> + +<H2> Pre-Release 1.1.0e (19 March 2002)</H2> +<UL> + +<P> +<LI> Added additional check for Windows/PC to filter/Nan.h. + +<P> +<LI> Upgraded zlib library to 1.1.4 (fix double free security hole). + +</UL> + + +<H2> Pre-Release 1.1.0e (27 February 2002)</H2> +<UL> + +<P> +<LI> Changed filter/process.[ch] to filter/zprocess.[ch] to avoid name +collision with Cygwin include file. + +<P> +<LI> Added -a switch to funhead to display all headers in a FITS file. + +</UL> + +<H2> Pre-Release 1.1.0e (11 February 2002)</H2> +<UL> + +<P> +<LI> Fixed filter parser so that it ignores ds9 "ruler" and "text" markers +only up to the first \n or ; (was ignoring to last \n). + +<P> +<LI> The NBLOCK parameter in fitsy/headdata.c was too large for Mac OS X +(max size of a declared char buf seems to be about .5 Mb). + +</UL> + +<H2> Beta Release 1.0.1b5 (31 January 2002)</H2> +<UL> + +<P> +<LI> Fixed bug introduced in calculated IRAF LTM values in 1.0.1b3. + +<P> +<LI> Fixed bug in filter parser giving wrong answers when two range +lists were combined with and explicit boolean operator: +<PRE> + $ fundisp $S"[x=512&&y=511,512]" +</PRE> +incorrectly acted like: +<PRE> + fundisp $S"[(x=512&&y=511)||(y=512)]" +</PRE> +instead of: +<PRE> + fundisp $S"[x=512&&(y=511||y=512)]" +</PRE> +In general, we recommend use of explicit parentheses. + +<P> +<LI> Fixed filter/NaN.h to recognize Compaq Alpha again (broken by their last change to cc). + +<P> +<LI> Removed redundant varargs definitions that conflicted with Alpha compiler definitions. + +<P> +<LI> Added blank line to inc.sed to work around Apple Mac OS X bug in which the +"i" (insert) command was treating final \\ as continuation \ in the text. + +<P> +<LI> Added include of mkrtemp.h to mkrtemp.c to get conditional compilation +for Mac OSX. + +<P> +<LI> Added support for --with-zlib to fitsy so that ds9 could use its own +copy of zlib (and not build the copy in fitsy). + +<P> +<LI> Removed config.cache and Makefile files from distribution tar file. + +</UL> + +<H2> Beta Release 1.0.1b4 (26 January 2002)</H2> +<UL> + +<P> +<LI> Make explicit that column filters are not permitted in an image +expression (such as the funcnts region arguments). + +<P> +<LI> Fix bug in region parser in which a region (without parens), +followed immediately by an operator: +<PRE> + circle 512 512 .5&&pi==1 +</PRE> +was not processing the final argument of the region correctly. + +<P> +<LI> Ignore new "tile" directive in filters (used by ds9). + +</UL> + +<H2> Beta Release 1.0.1b3 (4 January 2002)</H2> +<UL> + +<P> +<LI> Made modifications to Makefile.in to make releases easier. + +<P> +<LI> Added instructions Makefile.in so that funtools.h will always +have correct #defines for FUN_VERSION, FUN_MAJOR_VERSION, +FUN_MINOR_VERSION, and FUN_PATCH_LEVEL. + +<P> +<LI> Allow #include statements in funcalc program files. + +<P> +<LI> funimage now updates all 4 CDX_Y values by the block factor. + +<P> +<LI> Minor changes to make funtools work under darwin (Mac OS X). + +</UL> + +<H2> Beta Release 1.0.1b2 (14 November 2001)</H2> +<UL> + +<P> +<LI> Fixed FunOpen() bug (introduced in b1) in which filenames without +extensions SEGV'ed on open.

This means that all funtools programs now accept gzip'ed +files as valid input: +<PRE> + funcnts foo.fits.gz "circle 504 512 10" +</PRE> +It is no longer necessary to run gunzip and pipe the results to +stdin of a funtools program. + +<P> +<LI> Funtools tasks are now placed in a sub-menu in the DS9 Analysis +menu, instead of at the top level. + +<P> +<LI> Fixed a bug in funcnts in which the bottom-most pixel of a small +circle or annulus region could be missed when the region is only one +pixel wide for that value of y. + +<P> +<LI> Added -n switch to funhist so that table histograms could be +normalized by the width of the bin (val/(hi_edge-lo_edge)). + +<P> +<LI> Added -T switch to fundisp, funcnts, funhist to output in +starbase/rdb format (uses tabs instead of spaces between columns, +form-feeds between tables, etc.) + +<P> +<LI> Fixed a bug in which the field() region was not being properly +processed in combination with an image section.

The new script +supports gzip'ed files and bracket specifications on filenames at the +same time, which the direct call could not. Also the new script has +better error reporting. + +<P> +<LI> Replaced system() call used to compile filter and funcalc +expression with a special launch() call, which performs execvp() +directly without going through sh.
