A New Catalog of 30,239 1.4 GHz Sources
Abstract
Using the Green Bank 1.4 GHz Northern Sky Survey, we have generated a catalog of 30,239 sources over the declination range of -5^deg^ to 82^deg^ to a flux density limit of 100 microJy. Spectral indices were found for over 90% of these sources based on flux densities at 0.365 or 4.85 GHz taken from other catalogs. Flux densities at all three frequencies are available for 20,000 sources. The spectral properties of 1.4 GHz sources are discussed along with the selection effects induced by the idiosyncracies of the various catalogs.
