To possible users of the IDL Astronomy library
(http://idlastro.gsfc.nasa.gov)
I have made some updates to make this 17 year old IDL library somewhat
less antiquated. In particular, note that
1. The library now requires IDL V5.5 or later. All references to VMS
have been removed, and new features from V5.5 (e.g. file_search(),
strict_extra) have been added.
2. About 25 "stale" routines have been deleted (though they are still
available at http://idlastro.gsfc.nasa.gov/ftp/obsolete/ ) More
details are available at http://idlastro.gsfc.nasa.gov/ftp/news.txt
3. The FITS I/O routines now mostly use the /SWAP_IF_LITTLE_ENDIAN
keyword to OPEN to perform byteswapping on the fly. This should be
transparent to the user, unless a mix of old and new procedures is
used. For example, if the new FITS_OPEN is used with an old FITS_READ
then byteswapping will (incorrectly) be performed twice.
