From the information page of the US Naval Observatory:

" UCAC is an astrometric, observational program, which started in
" February 1998 at CTIO.

Information how to request the free 2-sided DVD is at the above URL.
I know of two programs that can function with this disk, XEphem and
CdC, and there may be others.

XEphem, the premier UNIX/Linux (and Windows/Cygwin) research program:
http://www.clearskyinstitute.com/xephem/
http://tech.groups.yahoo.com/group/xephem/

CdC (Cartes du Ciel aka SkyChart) for Linux and Windows:
http://www.ap-i.net/skychart/start
http://www.ap-i.net/skychart/en/news/ucac4_catalog

*****

FYI, XEphem runs natively in the Mac OS (BSD UNIX). It requires an
X-Windows environment such as Apple's X-11, which is standard with OS
10.7 and below. Beginning with 10.8 one must download and install
X-Quartz from http://xquartz.macosforge.org/landing/. XEphem has
installers that run under the standard Mac OS GUI.

Cartes du Ciel/Skychart, current version and latest beta, is also
available for Mac OS at http://www.ap-i.net/skychart/start.

I'm not absolutely certain about this, but I think that Aladin Sky
Atlas can also use the UCAC catalog. Aladin is a multi-purpose data
visualizer that is particularly handy for astrometry. It may be
downloaded at no charge for Linux, Mac OS, or Windows from
http://aladin.u-strasbg.fr, or it may be run as an applet in a web
browser.

Finally, Astroart for Windows is a versatile application that can do
astrometry as well. It supports the GSC, USNOB, and UCAC2 catalogs. It
may also support UCAC4, at least in future.

I agree with almost everything that you have said and almost everything that
you will say in your entire life.
