astro::fits::header::cfitsio
Astro::FITS::Header::CFITSIO(3pm) User Contributed Perl Documentation Astro::FITS::Header::CFITSIO(3pm)
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).
