Thanks Bill. I already had a calculation for GHA Aries, which is why I was asking for the SHA of stars. How long is the Almanac's data valid for? Even w/o it, it seems to me that at this point, if I could get my hands on some FK5 catalog data, I would be in business after looking at the NOVAS code. But all my searches on FK5 don't get me what I want :( Damn Internet ;-). So I keep looking... Another dumb question: how do I get from the name of a star to its # in a catalog like the one Ed Falk mentions? Thanks, YA
