I am exploring software for two-dimensional image processing, and
I have some questions about IRAF. I made copies of some of the
documents in your on-line archive, so I have an idea of what the
basic IRAF can do. Is there any way to find out what 3rd party
add-ons are available and what they can do? I will be dealing with
gamma ray data, and I am particularly interested in the Maximum
Entropy method. Thanks.

Patrick,

There is a listing of the add-on packages that are available from
NOAO listed at the end of each issue of the IRAF Newsletter. Volume 11
is just being sent out now, and a summary of that article is: The following software packages are available as add-ons to IRAF
versions 2.8, 2.9, and 2.9.1. All packages are available via file
transfer from the IRAF network archive on iraf.noao.edu (Internet
node 140.252.1.1) in the directory iraf.old and have readme files
containing instructions for transfer and installation. ARTDATA the new artificial data package.
IUEECHELLE prototype package to support a certain IUE echelle format
NEWIMRED new spectroscopic reduction packages for KPNO/CTIO instruments
DAOPHOT digital stellar photometry package
SAOimage X Window System based image display server for IRAF There is also volume rendering software, some IRAF demos, IRAF
networking Kernel server kits, and UISDISP display software for
VMS Workstations.In addition to these, other observatories have developed add-on packages,
some of which are probably of interest to you. The ROSAT group at the Center for Astrophysics has developed the
PROS package which is used with xray data (photon counting data). This
is a large packag with many capabilities; further information about it
can be obtained from Diana Worrall, dmw@cfa200.harvard.edu. The STSDAS package was developed at STScI for HST data, and it
contains many general image processing and data analysis tasks (including
some Fourier tools). There is a package of various deconvolution tasks
that are under consideration at STScI these days; the tasks are in the
"playpen" package, which is to indicate that these tasks are prototypes
and probably fairly volatile. There has been talk in the past of MEM
tasks appearing in STSDAS at some point. For more information, send a
request to sdas@stsci.edu, or just retrieve STSDAS via anonymous FTP
from stsci.edu There are some others as well. We have a package from CTIO that
you're probably not in much need of, and the EUVE group at Berkeley is
working on a package for analysis of data from their spacecraft as well.
I don't think the EUVE package is available at this point, but if you are
interested in their progress, you could request info from Carol Christian
(carolc@sag4.ssl.berkeley.edu). The IRAF Newsletters are available on-line in our FTP archive;
they are in the iraf/docs directory. Our archive is on node iraf.noao.edu
(140.252.4.1). If you want to receive paper copies of the Newsletters
via post, send your name and address information to iraf-requests@noao.edu.
