FXBHMAKE
Name
FXBHMAKE
Purpose
Create basic FITS binary table extension (BINTABLE) header.
Explanation
Creates a basic header array with all the required keywords, but with
none of the table columns defined. This defines a basic structure
which can then be added to or modified by other routines.
Use
FXBHMAKE, HEADER, NROWS [, EXTNAME [, COMMENT ]]
Inputs
NROWS = Number of rows in the binary table.
Opt. Inputs :
EXTNAME = If passed, then the EXTNAME record is added with this value.
COMMENT = Comment to go along with EXTNAME.
Outputs
HEADER = String array containing FITS extension header.
Opt. Outputs:
None.
Keywords
INITIALIZE = If set, then the header is completely initialized, and any
previous entries are lost.
DATE = If set, then the DATE keyword is added to the header.
EXTVER = Extension version number (integer).
EXTLEVEL = Extension level number (integer).
ERRMSG = If defined and passed, then any error messages will be
returned to the user in this parameter rather than
depending on the MESSAGE routine in IDL. If no errors are
encountered, then a null string is returned. In order to
use this feature, ERRMSG must be defined first, e.g.
ERRMSG = ''
FXBHMAKE, ERRMSG=ERRMSG, ...
IF ERRMSG NE '' THEN ...
Calls
GET_DATE, FXADDPAR, FXHCLEAN
Common :
None.
Restrictions
Warning: No checking is done of any of the parameters.
Side Effects
None.
