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.

NAME

       Astro::FITS::Header::CFITSIO - Manipulates FITS headers from a FITS file

SYNOPSIS

	 use Astro::FITS::Header::CFITSIO;

	 $header = new Astro::FITS::Header::CFITSIO( Cards => @array );
	 $header = new Astro::FITS::Header::CFITSIO( File => $file );
	 $header = new Astro::FITS::Header::CFITSIO( fitsID => $ifits );

	 $header->writehdr( File => $file );
	 $header->writehdr( fitsID => $ifits );

DESCRIPTION

       This module makes use of the CFITSIO module to read and write directly to a FITS HDU.

       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) and FITS identifier.

REVISION

       $Id$

METHODS

       configure
	   Reads a FITS header from a FITS HDU

	     $header->configure( Cards => @cards );
	     $header->configure( fitsID => $ifits );
	     $header->configure( File => $file );
	     $header->configure( File => $file, ReadOnly => $bool );

	   Accepts an FITS identifier or a filename. If both fitsID and File keys exist, fitsID key takes priority.

	   If "File" is specified, the file is normally opened in ReadWrite mode.  The "ReadOnly" argument takes a boolean value which determines
	   whether the file is opened ReadOnly.

       writehdr
	   Write a FITS header to a FITS file

	     $header->writehdr( File => $file );
	     $header->writehdr( fitsID => $ifits );

	   Its accepts a FITS identifier or a filename. If both fitsID and File keys exist, fitsID key takes priority.

	   Returns undef on error, true if the header was written successfully.

NOTES

       This module requires Pete Ratzlaff's Astro::FITS::CFITSIO module, and  William Pence's "cfitsio" subroutine library (v2.1 or greater).
