摘要：

The 91 m telescope in Green Bank was used during 1987 October to map 6.0 sr of sky in the 0-degrees < delta < + 75-degrees declination band at 4.85 GHz. We present the 87GB catalog of 54,579 discrete sources with angular sizes phi less-than-or-similar-to 10.5' and stronger than S approximately 25 mJy derived from these maps. The catalog positions and flux densities have been corrected for known map biases. Their estimated rms uncertainties were verified by comparison with more accurate positions and flux densities available for some sources. The 4.85 GHz normalized source counts S5/2n(S) between 25 mJy and 10Jy were obtained and agree well with evolutionary models based on independent data. The catalog is available in both printed and machine-readable versions.
