Описание: UCAC is an astrometric, observational program, which started in February 1998 at CTIO. All sky observations were completed at the Naval Observatory's Flagstaff Station in May 2004, and data reduction was completed in July 2009. The UCAC3 catalog was released on August 10, 2009 at the IAU General Assembly in Rio de Janero, Brazil. Bug fixes, reduction improvements, use of NPM data for proper motions and inclusion of APASS 5-band photometry lead to the final UCAC4.
