      2.1 Release
      Notes</h3>
    <ol>
      <h4> <b>Version 2.1</b></h4>
      <ol>
        <li> <tt>04.05.2002 fixed a problem with xpa contour load.</tt></li>
        <li> <tt>04.22.2002 ds9 version 2.1 released to the public.</tt></li>
      </ol>
      <h4> <b>Version 2.1b7</b></h4>
      <ol>
        <li> <tt>04.02.2002 upgrade to XPA 2.1.0e2. This fixes a
            problem
            with
            xpa and
            linux/linuxppc.</tt></li>
        <li> <tt>04.03.2002 fixed a problem with AST. plot.c, line
            19463,
            change parameter
            'force' from 1 to 0 in call to 'CheckLabels'. Sometimes we
            were seeing
            adj labels that where the same. This change makes sure that
            the labels
            are 'reduced' if we have this condition.</tt></li>
        <li> <tt>04.03.2002 ds9 will now automatically open as a bin
            table
            fits extension
            named EVENTS, STDEVT, and RAYEVENT.</tt></li>
        <li> <tt>04.03.2002 when trying to find an image to open in
            relax
            mode
            (ie the
            use did not specify an extension), ds9 will not find a valid
            image if
            the
            length of either axis is 0.</tt></li>
        <li> <tt>04.03.2002 now check for Ghostscript version 6.50 or
            higher
            when invoking
            Save As.</tt></li>
        <li> <tt>04.03.2002 add help application preference. Users can
            now
            choose between
            Netscape and Mozilla as the prefered help application.</tt></li>
        <li> <tt>04.04.2002 ds9 version 2.1b7 released to the public.</tt></li>
      </ol>
      <h4> <b>Version 2.1b6</b></h4>
      <ol>
        <li> <tt>02.04.2002 upgraded to ast version 1.8.6. Modified ast
            to
            use
            sscanf()
            for all platforms except Darwin. Darwin uses astSscanf(),
            which works
            around
            a problem with sscanf() on MacOSX, with format strings of
            the following
            format: sscanf(str, " %s %n", foo, &amp;nc).</tt></li>
        <li> <tt>02.04.2002 changed fity++ primary_/head_ header
            relationship.
            primary_
            is only set if there is a primary header is available and
            different
            from
            head_.</tt></li>
        <li> <tt>02.04.2002 wsc's are init'd with both the head_ and
            the
            primary_ (if
            available) to handle the case where wcs keywords are spread
            between hdu
            nd primary headers in mulitiple extension files.</tt></li>
        <li> <tt>02.06.2002 all xpa commands are now 'catch{}' to
            invoke a
            procedure
            that will unwind the watch cursor stack. Hopefully, no more
            stuck watch
            cursors.</tt></li>
        <li> <tt>02.07.2002 add <i>color</i> and <i>width</i>
            parameters
            to
            contours
            paste command. defaults are <i>green</i> and <i>1</i></tt></li>
        <li> <tt>02.08.2002 fixed a problem with the FRAME menu. It was
            cutting off
            the last separator.</tt></li>
        <li> <tt>02.12.2002 AST grid still does not support ICRS
            properly.
            When a user
            sets the coordinate system to ICRS, the actually parameters
            sent to the
            AST grid code is FK5</tt></li>
        <li> <tt>02.13.2002 for XPA points array, fits, regions, and
            wcs
            (fillbuf=false),
            manually flush the buffer at the end to make sure no data is
            left</tt></li>
        <li> <tt>02.13.2002 ecliptic coords from wcssubs corrected by
            new
            version of
            wcs/wcscon.c</tt></li>
        <li> <tt>02.13.2002 AST grids, corrected the MDJ-OBS keyword
            generated
            to generate
            the correct EPOCH.</tt></li>
        <li> <tt>02.13.2002 adjusted the EQUINOX value for ECLIPTIC
            coords
            for
            ast grids
            to agree with wcssubs. Seems for ecliptic coords, wcssubs
            and ast use
            two
            slightly different interpretations of the EQUINOX value.</tt></li>
        <li> <tt>02.13.2002 fixed a problem with histogram equalization
            introduced in
            version 2.1b5.</tt></li>
        <li> <tt>02.14.2002 fixed a problem with titles in plot(stdin).
            We
            now
            take
            the first line, and starting from the end, pick off the
            dimension, x
            and
            y axis titles, and the remainder is taken as the plot title.
            It can
            contain
            spaces and special characters such as '[]'</tt></li>
        <li> <tt>02.14.2002 add 'Always create new plot' option to
            prefs</tt></li>
        <li> <tt>02.14.2002 add multiple analysis plots, unless prefs
            are
            unset</tt></li>
        <li> <tt>02.14.2002 change default annulus and panda to 1
            annuli</tt></li>
        <li> <tt>02.14.2002 enable multiple array loads via blueplate
            dialog</tt></li>
        <li> <tt>02.14.2002 reset,append, and replace wcs now processes
            OBJECT
            keyword</tt></li>
        <li> <tt>02.15.2002 fixed a problem with grid format of
            degrees.
            Sometimes,
            the incorrect format would be used. This was corrected by
            up'ng the
            number
            of digits displayed to d.3</tt></li>
        <li> <tt>02.21.2002 upgraded to AST 1.8.7</tt></li>
        <li> <tt>02.21.2002 upgraded to WCS 3.0.7</tt></li>
        <li> <tt>02.22.2002 fixed a problem with Ascii Tables in
            fitsy++.
            The
            column
            offset is now calculated from TBCOLn if present.</tt></li>
        <li> <tt>02.22.2002 simplied columns in fitsy++. Now all
            columns
            have
            a value(char*
            ptr, int i) and str(char* ptr, int i) procedure.</tt></li>
        <li> <tt>02.22.2002 add support for HST WFPC2 mosaics</tt></li>
        <li> <tt>02.25.2002 fixed a problem with 'marker command'. The
            command
            STRING
            must be quoted by '\{' '\}' before being pasted to the Frame
            parser.</tt></li>
        <li> <tt>02.26.2002 add $ERROR/ERROR: support for analysis
            $plot(stdin) macro.</tt></li>
        <li> <tt>02.26.2002 analysis menus now support multiple levels
            of
            hierarchical
            menus</tt></li>
        <li> <tt>02.26.2002 multiple hierarchical menus may have the
            same
            label</tt></li>
        <li> <tt>02.26.2002 hierarchical menu label may have an
            imbedded
            spaces</tt></li>

            macro</tt></li>
        <li> <tt>02.27.2002 add xpa get fits [type|image|table] command</tt></li>
        <li> <tt>02.27.2002 minor tweak with the File:Save as menu</tt></li>
