This files are an extraction of the UCAC3 star catalog (Zacharias et al. 2009)* for use with the Skychart software. They contain only a part of the original catalog data extracted by the u3conv program**. For each star it include: identifier, RA, Dec, aperture magnitude, proper motion, approximate color index***. Only the stars not in Tycho2 and fainter than magnitude 10 are include. So you must always activate the Tycho2 along with this catalog.
