The GB6 Catalog of Radio Sources
Abstract
The Green Bank 4.85 GHz (λ ~ 6 cm) survey was made with the NRAO seven-beam receiver on the (former) 91 m telescope during 1986 November and 1987 October. The final set of sky maps covering the declination band 0^deg^ < δ < +75^deg^ was constructed with data from both epochs. Its noise and position errors are nearly a factor of2^1/2^ smaller than in the epoch 1987 maps, from which the 87GB catalog of 54,579 sources stronger than S ~ 25 mJy was extracted. Therefore, we used the new maps to make the GB6 catalog of 75,162 discrete sources with angular sizes φ <= 10.5' and flux densities S >= 18 mJy. This catalog is available in machine-readable versions with either B1950 or J2000 positions and as a printed book with B1950 positions. The GB6 weighted differential source counts S^5/2^n(S) between 18 mJy and 7 Jy agree well with evolutionary models based on independent data.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
