Abstract

Results of observations of the sky north of delta = -40 deg in the 21-cm line of atomic hydrogen are reported. The survey covers a velocity range of 654 km/s centered on the Galactic standard of rest, with 5.3-km/s wide filters. Calibration and reduction of the observations are described. The survey is presented as a series of images of the sky, each covering a 10-km/s wide velocity range. This survey is distinguished by its sensitivity to low surface brightness features (TA is approximately equal to 50 mK) and relative freedom from sidelobe contamination. High-velocity clouds are extracted and cataloged automatically. At the resolution of the survey, the lowest H I column density in the sky is 5.7 x 10 exp 19/cm.

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.
