Hipparcos catalog
Posted: 13.08.2002, 09:15
Hello,
I am Celestia fan and also an OS X new cocoa programmer. I wish to write a star editor for Celestia.
Does anybody knows why the Hipparcos astrometric catalog contains 118218 stars and the stars catalog of Celestia only 112521 ?
and also why HIP 118322 is duplicated at the end of the file stars.dat ?
(see : http://tdc-www.harvard.edu/software/cat ... arcos.html)
Thank you
