Astro::FITS::Header::GUser)Contributed Perl DocumenAstro::FITS::Header::GSD(3)

NAME
       Astro::FITS::Header::GSD	- Manipulate FITS headers from GSD files

SYNOPSIS
	 use Astro::FITS::Header::GSD;

	 $hdr =	new Astro::FITS::Header::GSD( Cards => \@cards );
	 $hdr =	new Astro::FITS::Header::GSD( gsdobj =>	$gsd );
	 $hdr =	new Astro::FITS::Header::GSD( File => $file );

DESCRIPTION
       This module makes use of	the Starlink GSD module	to read	from a GSD
       header.

       It stores information about a FITS header block in an object. Takes an
       hash as an argument, with either	an array reference pointing to an
       array of	FITS header cards, or a	filename, or (alternatively) a GSD
       object.

METHODS
       configure
	   Reads a header from a GSD file.

	     $hdr->configure( Cards => \@cards );
	     $hdr->configure( Items => \@items );
	     $hdr->configure( gsdobj =>	$gsd );
	     $hdr->configure( File => $filename	);

	   Accepts a GSD object	or a filename. If both "gsdobj"	and "File"
	   keys	exist, "gsdobj"	key takes priority.

       writehdr
	   The GSD library is read-only. The writehdr method is	not
	   implemented for this	sub-class.

NOTES
       This module requires the	Starlink GSD module.

       GSD supports keys that are longer than the 8 characters allowed as part
       of the FITS standard. GSD keys are truncated to 8 characters by this
       module.
