Each line contains the star name (If no actual name, then the Flamsteed
letter and constellation. If no Flamsteed, then Henry Draper number. If
no HD then Hipparcos number).
The next three numbers are hours, minutes, seconds of the Right
Ascension.
The next three numbers are degrees, minutes, seconds of the Declination.
(Note, only the degrees show the sign but you'll have to remember to
apply it to the degrees and seconds).
The final number is the base magnitude, which indicates the brightness
of the star.
Convert the Right Ascension and Declination to degrees. Place the star a
long distance away in the z direction. Rotate by -x*RA then y*Dec (or is
it -y*Dec).
