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 \s-1GSD\s0 module to read from a \s-1GSD\s0 header.

It stores information about a \s-1FITS\s0 header block in an object. Takes an hash as an argument, with either an array reference pointing to an array of \s-1FITS\s0 header cards, or a filename, or (alternatively) a \s-1GSD\s0 object.

METHODS

configure: Reads a header from a \s-1GSD\s0 file. $hdr->configure( Cards => \@cards ); $hdr->configure( Items => \@items ); $hdr->configure( gsdobj => $gsd ); $hdr->configure( File => $filename ); Accepts a \s-1GSD\s0 object or a filename. If both \*(C`gsdobj\*(C' and \*(C`File\*(C' keys exist, \*(C`gsdobj\*(C' key takes priority.
writehdr: The \s-1GSD\s0 library is read-only. The writehdr method is not implemented for this sub-class.

NOTES

This module requires the Starlink \s-1GSD\s0 module.

\s-1GSD\s0 supports keys that are longer than the 8 characters allowed as part of the \s-1FITS\s0 standard. \s-1GSD\s0 keys are truncated to 8 characters by this module.
