Astro::FITS::Header::AST - Manipulates FITS headers from an AST object

SYNOPSIS

Top

  use Astro::FITS::Header::AST;

  $header = new Astro::FITS::Header::AST( FrameSet => $wcsinfo );
  $header = new Astro::FITS::Header::AST( FrameSet => $wcsinfo,
                                          Encoding => 'FITS-IRAF' );

  $header = new Astro::FITS::Header::AST( Cards => \@cards );

DESCRIPTION

Top

This module makes use of the Starlink::AST module to read the FITS HDU from an AST FrameSet object.

It stores information about a FITS header block in an object. Takes an hash as an arguement, with an array reference pointing to an Starlink::AST FramSet object.

REVISION

$Id$

METHODS

Top

configure

Reads a FITS header from a Starlink::AST FrameSet object

  $header->configure( FrameSet => $wcsinfo );

Base class initialisation also works:

  $header->configure( Cards => \@cards );

Accepts a reference to an Starlink::AST FrameSet object.

If a specific encoding is required, this can be specified using the Encoding argument. Default is FITS-WCS if no Encoding is given. Note that not all framesets can be encoded using FITS-WCS.

  $header->configure( FrameSet => $wcsinfo, Encoding => "Native" );

If Encoding is specified but undefined, the default will be decided by AST.
