I found this data set on the internet so long ago I'm not sure where it came
from. I think it includes the Hipparcos data, (judging by all the stars
named Hip xxxxx)
I have it in Quattro Pro spreadsheet format.

For some reason my H&E has quit working  :(,  so I may wind up constructing
a set of world-building rules almost from scratch. Unless I can find a
world-building site on the net that's already done it better.
