Description:
The survey contains 144 maps that cover the declination zone -5 to +82
degrees from the National Radio Astronomy Observatory (NRAO) 1400-MHz
survey. The observations were made during 1983 April 2-21, and in
October 1983, with the rebuilt four-feed receiver on the NRAO 91-m
transit telescope in Green Bank. Its resolution is 12.7x11.1 arcmin.
These maps with a pixel size of 2x2arcmin contain 3000 sources per sr
stronger than 0.15 Jy, which is six times the rms noise. They are
available in the Flexible Image Transport System (FITS) standard (in
the "maps" subdirectory) and can be studied with standard Astronomical
Image Processing System (AIPS) display and analysis programs.
