The NVSS is being made as a service to the astronomical community, and the principal data products are being released into a directory accessible by anonymous FTP as soon as they are produced and verified. To ensure equal access for everyone, the NVSS team members have agreed to use only these electronically released results for their own research.
Unprocessed data are available on request.
Each map is named by the J2000 right ascension and declination of its center. A description of the contents and interpretation of this catalog is given in the postscript document catalog.ps. Each survey image also has an attached binary table containing the sources derived from that image. Gzipped files are uncompressed using gunzip which is available for most computer systems. For users with only PCs, Bill Cotton has recently released FITSview for MS Windows.
