NRAO VLA D-array Sky Survey (NVSS)
The National Radio Astronomy Observatory (NRAO) observed the sky north of declination -40° using the Very Large Array (VLA) (D-array) at the 1.4 GHz frequency. We present the total intensity survey, covering 82% of the sky, at an angular resolution of 45“. Units of the map are Jy/beam.
