Astro::FITS::Header::CFITSIO(3) 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).
