NVSS   (NRAO VLA Sky Survey)
 Write:<<NVSS  JHHMMSS+DDMMSSa>>  

        <<NVSS  BHHMMSS+DDMMSS>>
 N:  1773484
Object:(Rad)  (SIMBAD class: Radio = Radio Source)
  Note:The NVSS source list is too large (about 2x106 lines) to print    on paper. It will appear only on the WWW or digital copies of the    http://www.nrao.edu website.    
    The NVSS source at J2000 00 00 00.24 -20 04 49.2 = B1950 23 57 26.34 -20 21 31.5    is called NVSS J000000-200449 or NVSS B235726-202131.    
    There are four cases where there are pairs of sources which are so    close together that their names would be identical according to this    schema, and the HEASARC has added suffixes of 'a' (for the source with    the smaller RA) and 'b' (for the source with the larger RA) in such    cases in order to differentiate them.
