NAME

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

SYNOPSIS

	 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

       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 argument, with an array reference pointing to an
       Starlink::AST FramSet object.

REVISION

       $Id$

METHODS

       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.
