If \*(L"stdin\*(R" is specified, data are read from +the standard input. Funtools Bracket +Notation is used to specify particular \s-1FITS\s0 extension to process. +Normally, the full 80 characters of each header card is output, +followed by a new\-line. +.PP +If the \fB\-a\fR switch is specified, the header from each \s-1FITS\s0 +extensions in the file is displayed. Note, however, that the \fB\-a\fR +switch does not work with \s-1FITS\s0 files input via stdin. We hope to +remove this restriction in a future release. +.PP +If the \fB\-s\fR switch is specified, only 79 characters are output +before the new\-line. This helps the display on 80 character terminals. +.PP +If the \fB\-t\fR switch is specified, the data type of the parameter +is output as a one character prefix, followed by 77 characters of the +param. The parameter data types are defined as: \s-1FUN_PAR_UNKNOWN\s0 +('u'), \s-1FUN_PAR_COMMENT\s0 ('c'), \s-1FUN_PAR_LOGICAL\s0 ('l'), \s-1FUN_PAR_INTEGER\s0 +('i'), \s-1FUN_PAR_STRING\s0 ('s'), \s-1FUN_PAR_REAL\s0 ('r'), \s-1FUN_PAR_COMPLEX\s0 ('x'). +.PP +If the \fB\-L\fR (rdb table) switch is used, the output will conform +to starbase/rdb data base list format. +.PP +For example to display the \s-1EVENTS\s0 extension (binary table): +.PP +.Vb 17 +\& [sh] funhead "foo.fits[EVENTS]" +\& XTENSION= 'BINTABLE' / FITS 3D BINARY TABLE +\& BITPIX = 8 / Binary data +\& NAXIS = 2 / Table is a matrix +\& NAXIS1 = 20 / Width of table in bytes +\& NAXIS2 = 30760 / Number of entries in table +\& PCOUNT = 0 / Random parameter count +\& GCOUNT = 1 / Group count +\& TFIELDS = 7 / Number of fields in each row +\& EXTNAME = 'EVENTS ' / Table name +\& EXTVER = 1 / Version number of table +\& TFORM1 = '1I ' / Data type for field +\& TTYPE1 = 'X ' / Label for field +\& TUNIT1 = ' ' / Physical units for field +\& TFORM2 = '1I ' / Data type for field +\& etc. ... +\& END +.Ve +.PP +To display the third header: +.PP +.Vb 14 +\& [sh] funhead "foo.fits[3]" +\& XTENSION= 'BINTABLE' / FITS 3D BINARY TABLE +\& BITPIX = 8 / Binary data +\& NAXIS = 2 / Table is a matrix +\& NAXIS1 = 32 / Width of table in bytes +\& NAXIS2 = 40 / Number of entries in table +\& PCOUNT = 0 / Random parameter count +\& GCOUNT = 1 / Group count +\& TFIELDS = 7 / Number of fields in each row +\& EXTNAME = 'TGR ' / Table name +\& EXTVER = 1 / Version number of table +\& TFORM1 = '1D ' / Data type for field +\& etc. ... +\& END +.Ve +.PP +To display the primary header (i.e., extension 0): +.PP +.Vb 8 +\& sh> funhead "coma.fits[0]" +\& SIMPLE = T /STANDARD FITS FORMAT +\& BITPIX = 16 /2-BYTE TWOS-COMPL INTEGER +\& NAXIS = 2 /NUMBER OF AXES +\& NAXIS1 = 800 / +\& NAXIS2 = 800 / +\& DATATYPE= 'INTEGER*2' /SHORT INTEGER +\& END +.Ve +.PP +The funhead program also can edit (i.e. add, delete, or modify) or +display individual headers parameters. Edit mode is signalled by the +presence of two additional command-line arguments: output file and +edit command file, in that order. Edit mode acts as a filter: the +output file will contain the entire input \s-1FITS\s0 file, including other +extensions. The edit command file can be \*(L"stdin\*(R", in which case edit +command are read from the standard input. +.PP +The edit command file contains parameter comments (having '#' in the +first column) and delete and assignment(modify or add) operations. A +delete operation is specified by preceding the parameter name with a +minus sign \*(L"\-\*(R". A display operation (very useful in interactive +sessions, i.e., where the edit commands are taken from stdin) is +specified by preceding the parameter name with a question mark \*(L"?\*(R". In +either case, a parameter value need not be specified. An assignment +operation is specified in the same two ways that a parameter is +specified in a text header (but without the comment character that +precedes header params), i.e.: +.IP "\(bu" 4 +FITS-style comments have an equal sign \*(L"=\*(R" between the keyword and +value and an optional slash \*(L"/\*(R" to signify a comment. The strict \s-1FITS\s0 +rules on column positions are not enforced. +.IP "\(bu" 4 +Free-form comments can have an optional colon separator between the +keyword and value. In the absence of quote, all tokens after the +keyword are part of the value, i.e. no comment is allowed. +.PP +For example, the following interactive session checks for the +existence of parameters, adds new parameters, modifies them, and +modifies and deletes existing parameters: +.PP +.Vb 20 +\& sh$ ./funhead snr.ev foo.fits - +\& # look for FOO1 +\& ?
