- Form: FITS buf [FLOAT=name] float_value
-
- FITS buf [INT=name] integer_value
-
- FITS buf [CHAR=name] 'character string'
-
- FITS PROF [FLOAT=name float] [INT=name in] [CHAR=name char]
Use one of these forms to insert a new FITS header card into the image
header, or to change the value of an existing FITS header card. If you
specify the optional PROF keyword rather than a buffer number, the new
header card will be inserted into the internal PROFILE header (see PROFILE
and SAVE PROF). The FITS keyword name may be no longer than 8 characters.
Except for two special cases, a FITS card already in the header with the
same name will be replaced. The two exceptions are CHAR=COMMENT and
CHAR=HISTORY, which will always add a new COMMENT or HISTORY card,
respectively, to the header.
The float_value for the FLOAT keyword should be a floating point constant
or an arithmetic expression. The integer_value for the INT keyword should
be an integer constant or an arithmetic expression whose result will be
rounded to the nearest integer.
Examples:
- FITS 1 FLOAT=AIRMASS 1.3
- Inserts a FITS header card named
AIRMASS with value 1.3 into the header of the image in buffer 1.
- FITS 3 CHAR=COMMENT 'My best observation ever'
-
Inserts a new COMMENT card into he header of the image in buffer 3.
