Hi All,
I am writing an anonymous structure (52 columns by 21 rows) out to a
FITS file, using mwrfits.pro from the astrolib library. When I take
that file and read it back in (from the same machine), I get garbage
values throughout the
structure. Nans, infs and just random longs... very confusing.
Neither program complains, and until now, both have worked
spectacularly.
I have noticed that the first row is preserved properly, and that I
can isolate a single row and write it out, then read it in, and it is
ok.
Any suggestions??
Thank you!

Marc,
In my April post, I was referring to the bug (ID: 2982679) that
you evidently fixed on 10-04-10
http://sourceforge.net/tracker/?func=detail&aid=2982679& amp;group_id=97659&atid=618683
Thanks for your work on GDL! --Wayne

I'm late to the party here, but I was having the same problem as
John. Updating my goddard library fixed the problem (as far as I can
tell), but I'm still unsure of the root of the original problem.
Doesn't matter now, though, I suppose! Thanks!
