Astro::FITS::Header::AST.3pm

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 arguement, 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.
