Catalog Coverage Maps

June 14, 2010
Catalog Coverage Maps The National Virtual Observatory's "Sky Statistics Service" allows astronomers to get a fast inventory of astronomical objects from various catalogs. These catalogs can be wavelength-based (x-ray sources, radio sources, etc.), phenomena-based (supernova remnants, planetary nebulae, variable stars, quasars, etc.), or may simply show where a telescope has been pointed (HST observation log, ESO observation log, etc.). The Sky Statistics Service also allows astronomers to easily determine regions of overlap between catalogs. These images show the distribution of objects in a sample of the many astronomical catalogs that are accessible through the National Virtual Observatory. This research was supported by National Science Foundation grant AST 01-22449. (Date of Image: January 2006)
