The NRAO VLA Sky Survey
Open accessAbstract
The NRAO VLA Sky Survey (NVSS) covers the sky north of J2000.0 δ = -40° (82% of the celestial sphere) at 1.4 GHz. The principal data products are (1) a set of 2326 4° × 4° continuum "cubes" with three planes containing Stokes I , Q , and U images plus (2) a catalog of almost 2 × 10 6 discrete sources stronger than S ≈ 2.5 mJy. The images all have θ = 45'' FWHM resolution and nearly uniform sensitivity. Their rms brightness fluctuations are σ ≈ 0.45 mJy beam -1 ≈ 0.14 K (Stokes I ) and σ ≈ 0.29 mJy beam -1 ≈ 0.09 K (Stokes Q and U ). The rms uncertainties in right ascension and declination vary from ≲1'' for the N ≈ 4 × 10 5 sources stronger than 15 mJy to 7'' at the survey limit. The NVSS was made as a service to the astronomical community. All data products, user software, and updates are being released via the World Wide Web as soon as they are produced and verified.

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.
