USNO-B Catalog ConeSearch
Description
USNO-B is an all-sky catalog that presents positions, proper motions, magnitudes in various opticalpassbands, and star/galaxy estimators for 1,042,618,261 objects derived from 3,643,201,733 separateobservations. The data were obtained from scans of 7435 Schmidt plates taken for the various sky surveysduring the last 50 years. USNO-B1.0 is believed to provide all-sky coverage, completeness down to V = 21,0>2 astrometric accuracy at J2000, 0.3 mag photometric accuracy in up to five colors, and 85% accuracy fordistinguishing stars from nonstellar objects.A more detailed description of the construction and contents of the USNO-B1 catalog can be found in Monet et al. (2003, "The USNO-B Catalog", AJ, 125, 984), http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/usno-b1.0/resolveuid/41be0c1a4d1a8372289bad3baf27cde5.A mirror of USNOB exists in the MAST holdings and is thus available as a cone search.All available catalogs are listed at http://archive.stsci.edu/vo/mast_services.html.
