Astro::FITS::Header::GSD - Manipulate FITS headers from GSD files
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 );
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.
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.
The GSD library is read-only. The writehdr method is not implemented for this sub-class.
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.
