USNO CCD Astrograph Catalog - South

Abstract

Project Summary: In January 1998, the US Naval Observatory started an astrometric survey at Cerro Tololo, Chile. The survey will be used to produce the USNO CCD Astrograph Catalog - South (UCAC-S). The telescope, originally designed for photography, uses a 4k CCD camera which gives a one degree field at o.9"/pixel scale. The combination of the one square degree field and small aperture works well to provide good coverage of the reference star density and brightness from the Hipparcos/Tycho/ACT catalogs. Longer exposures (200 seconds) of areas around quasars will be used with data taken with the CTIO 0.9-m reflector to link the UCAC positions to the ICRF.
