    Re: Algorithm for star ephemerides?

    > Another dumb question: how do I get from the name of a star to its # in a
    catalog like the one Ed Falk mentions?
    
    And here's an answer to myself, for the record: VizieR does. See
    http://adc.gsfc.nasa.gov/vizier/. If you go to http://vizier.u-strasbg.fr/
    and then for example enter Regulus in the Target name box, then click Find
    Data, you'll get numbers that match Meeus' AA 1st ed. p. 124 (from the
    I/146/ppm1 catalog):

    (and that also seems to answer my FK5 question).
    
    Now, I have another small question: where is the name of the star in all
    this data? Even clicking to get detail doesn't give the name (neither
    Regulus nor Alpha Leonis or even just Leonis are in the page). How can I
    then check that I really got what I wanted?
    
    YA
