Astro::FITS::Header::CFITSIO - Manipulates FITS headers from a FITS file
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 );
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 arguement, with either an array reference pointing to an array of FITS header cards, or a filename, or (alternatively) and FITS identifier.
$Id$
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.
File
ReadOnly
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.
This module requires Pete Ratzlaff's Astro::FITS::CFITSIO module, and William Pence's cfitsio subroutine library (v2.1 or greater).
