Abstract:
The Second Cape Photographic Catalogue (CPC2) is an astrometric,
photographic catalog covering the entire Southern Hemisphere to a
limiting magnitude of about 10.5. The Hipparcos Catalogue has been
used for a new, plate-by-plate, rigorous reduction. A significant
improvement over the release 1 version of the data was achieved. With
an average accuracy of 53 mas and a mean epoch of 1968, the CPC2 is a
key catalog for proper-motion determination. This release 2 of the
CPC2 contains high-quality positions of 266629 stars and an appendix
of 8040 other stars. Catalog reduction and construction details are
given, as well as a description of the final product, which is
available from the US Naval Observatory.
