    Re: Any "on line" Star Position Computation available ?

    It may not be SIMBAD. I see things I don't understand direct from Vizier as well:


    00 43 35.37 -17 59 11.8 VizieR Hipparcos I/311/hip2 at 2000.0
    00 43 35.228 -17 59 12.06 VizieR Hipparcos I/311/hip2 at 1991.25
    00 43 35.371 -17 59 11.78 vizier UCAC2 BSS I/294A at 2000.0
    00 43 35.237 -17 59 12.04 vizier Tycho-2 I/259 at 1991.8
    00 43 35.36352 -17 59 11.7636 vizier 2MASS II/246 at 1998.6
    00 43 35.37145 -17 59 11.77811 vizier FK6 I/264/fk6_1 2000.0
    00 43 35.237 -17 59 12.04 visier GSC I/305/out 2000.0
    00 43 35.2368 -17 59 12.0516 visier USNOB-1.0 I/284 2000

    Sometimes, it seems the Vizier move to 2000 isn't right (for example,it warns it is applying PM's, but the PM's are zero, so there is no change), so when possible, I took the observed RA and Dec with the Epoch of observation.

    I may be missing something.
