NAME

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

CONTENTS

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

<B>configureB> 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.

<B>writehdrB> 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.
