Abstract

This catalog contains a list of 30239 radio sources at 1.4GHz over the declination range of -5 to +82 degrees. This catalog is based on the Green Bank 1.4GHz Northern Sky Survey (Condon and Broderick, 1986, Cat. VIII/6) which was generated using the Green Bank 300 foot (91m) telescope. The threshold for identifying a 1.4GHz radio source was set at 100mJy. The catalog data include the source name, a confusion flag, right ascension (1950), declination (1950), 1.4GHz flux, a flag to indicate if the source is extended at 20cm, 4.85GHz flux (from Becker et al., 1991, Cat. VIII/13), a flag to indicate if the source is extended at 6cm, 365MHz flux (from the Texas Survey, Douglas et al. 1980; see Cat. VIII/42)), spectral index between 6 and 20 cm, and spectral index between 20 and 80 cm. Where possible, the source name is derived from the 6cm catalog of Becker et al. 1991 (Cat. VIII/13).
