SkyView has copied the NVSS intensity data from the NRAO FTP site. The full NVSS survey data includes information on other Stokes parameters.

Observations for the 1.4 GHz NRAO VLA Sky Survey (NVSS) began in 1993
September and should cover the sky north of -40 deg declination (82%
of the celestial sphere) before the end of 1996. The principal data
products are:

A set of 2326 continuum map "cubes," each covering 4 deg X 4 deg with three planes containing Stokes I, Q, and U images. These maps
were made with a relatively large restoring beam (45 arcsec FWHM) to yield the high surface-brightness sensitivity needed for completeness and photometric accuracy. Their rms brightness fluctuations are
about 0.45 mJy/beam = 0.14 K (Stokes I) and 0.29 mJy/beam = 0.09 K
(Stokes Q and U). The rms uncertainties in right ascension and
declination vary from 0.3 arcsec for strong (S > 30 mJy) point
sources to 5 arcsec for the faintest (S = 2.5 mJy) detectable
sources.

Lists of discrete sources.

The NVSS is being made as a service to the astronomical community, and
the data products are being released as soon as they are produced and
verified.

The NVSS survey is included on the SkyView High Resolution Radio Coverage map. This map shows coverage on an Aitoff projection of the sky in equatorial coordinates.
