    Re: Any "on line" Star Position Computation available ?
    From: Dave Walden

    Andres' results seem inconsistent. With UT1=UT, I get:

    IAU 2000
    14 6 43.498918
    IAU 2000 with truncated nutation
    14 6 43.498848
    IAU 2000 and 2006
    14 6 43.498908
    IAU 1982/94
    14 6 43.499347

    With what seems to be Andres' input data, UT1-UTC=.23339:

    IAU 2000
    14 6 43.732947
    IAU 2000 with truncated nutation
    14 6 43.732877
    IAU 2000 and 2006
    14 6 43.732936
    IAU 1982/94
    14 6 43.733379

    Maybe I'd better check my results!
