A Green Bank Sky Survey in Search of Radio Sources at 1400 MHz. III. Positions and Flux Densities of the GB Radio Sources

A continuum 1400 MHz survey with the NRAO 300-foot radiotelescope has been made between right ascensions 7^h17^m to 16^h23^m, fully covering the declination range +45.8 arcdeg to +51.7 arcdeg. The survey covers about 521 square degrees of the sky. Results are presented by a list of 1086 radio sources down to a limiting flux density of 0.09x10^-26 W m^-2 Hz^-1 at 1400 MHz. Among these sources, 821 were previously uncatalogued. A study has been made of the spectral index distribution for sources common to the present survey and the BP catalogue (Bailey and Pooley 1968). No change in the mean spectral index with flux density has been found for the BP sources selected at 408 MHz. Differential counts of radio sources at 1400 MHz are presented in the form of a graph and compared with those at 1415 MHz derived from the Ohio Survey (Harris and Kraus 1970). Observational and reduction procedures are also discussed.
