RE: H*e*l*p Needed

Tom,

I'd be happy to help you, and send you some code.  But, you will have to
install CFITSIO first
(http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html).  Then
preferablly, you would also install CFITSIO.pm
(http://search.cpan.org/search?mode=module&query=CFITSIO).

Then I can easily help you write C or Perl code which will do what you want.

Cheers,
Rob
