part of his work for the Starlink Project (http://www.starlink.ac.uk/), and
Tim Jenness <timj@jach.hawaii.edu> of the Joint Astronomy Center (JAC)
(http://www.jach.hawaii.edu/) in Hawaii.

This version of the module includes patches supplied by Diab Jerius
<dj@head-cfa.harvard.edu>, of the Harvard-Smithsonian Center for Astrophysics,
and by Jim Lewis <jrl@ast.cam.ac.uk>, of the Cambridge Astronomy Survey Unit
at the Institute of Astronomy, to allow access to Multi-Extension FITS files.

The tied interface was updated for version 2.x by Craig DeForest
<deforest@boulder.swri.edu> of the Department of Space Studies, Southwest
Research Institute and Tim Jenness <timj@jach.hawaii.edu> of the Joint
Astronomy Center (JAC) in Hawaii. Patches to fix some bugs in the tied
interface when dealing with blank cards were supplied by Brad Cavangh

lib/Astro/FITS/Header/Item.pm  view on Meta::CPAN

=begin __private

=item B<_stringify>

Internal routine to generate a FITS header card using the contents of
the object. This rouinte should not be called directly. Use the
C<card> method to retrieve the contents.

  $card = $item->_stringify;

The object state is not updated by this routine.

This routine is only called if the card cache has been cleared.

If this item points to a sub-header the stringification returns
a comment indicating that we have a sub header. In the future
this behaviour may change (either to return nothing, or
to return the stringified header itself).
