I wrote a very Q&D version some time back... hmmm 2 years back, now that I look at it. It's available by anon. ftp from sequoia.lle.rochester.edu (128.151.32.185), in pub, called readfits.pro. Send additions/corrections, etc. to me at the address below. Technically this code is the property of the University of Rochester, but it's not even complex enough to bother with a copyright notice. If you sell it and make millions, you should probably donate some of it to the UofR :-). -steve -- +---------+------------------------------------------------- -------+---------+ | | Steve Swales (716) 275-7730,-3194,-5101 | | | | steve@aldur.lle.rochester.edu (128.151.32.171) | | | | University of Rochester 250 East River Road | | | | Laboratory for Laser Energetics Rochester, NY 14623 | | +---------+------------------------------------------------- -------+---------+

The problem was that one of the procedures called by READFITS had been inadvertantly left in. If that procedure (sxaddpar) is removed from the FITS directory (I think) READFITS should work. The correct version is in the SDAS directory. JAyant Murthy Johns Hopkins, Dept of Physics

description: Here is what I know about the problems with the IDL FITS I/O procedures in the FTP anonymous directory on idlastro.gsfc.nasa.gov Between May 19 - May 21 the directory contained the following buggy procedures: 1. As mentioned by Jayant Murthy, the procedure SXADDPAR in the /fits directory was obsolete, although the one in the /sdas directory was correct. 2. The procedure WRITEFITS had a couple of typos preventing compilation. Both of the above problems are now fixed. The COBE group has had some additional problems writing floating point VMS FITS data under V2.2.1. I would encourage VMS users of floating point FITS data to upgrade to at least V2.2.2 (the current version is V2.3.0) to take advantage of the new XDR keywords to the BYTEORDER function. I would appreciate hearing about any other problems with the FITS I/O procedures. Wayne Landsman landsman@stars.gsfc.nasa.gov
