Description:
   The catalog was compiled from images obtained by the NRL Far-Ultraviolet
   camera/spectrograph operated from the lunar surface from 21-23 April 1972
   during the Apollo 16 mission.  The catalog was prepared by scanning the
   images on a microdensitometer and recording its output on tape.  The
   Revised S201 Catalog differs from the first edition (Page, Carruthers, and
   Hill 1978) in that the brightnesses of all detected objects have been
   transformed to an absolute scale of UV magnitudes based on instrumental
   preflight calibrations.  Positional errors of the detected images are less
   than or of order 3 arcminutes.  Reference 1 should be consulted for more
   detailed information concerning the instrumentation used, data reduction
   and analysis, and comparison with stellar models and with other UV
   catalogs.  The machine catalog contains data for 11 fields; individual data
   records include information such as running number of the object in the
   field, exposure time for the image, filter used, scan coordinates,
   equatorial position, object identification, differences between measured
   and catalog coordinates, spectral type, SAO or other visual and
   photographic magnitudes, peak density, pixel, background and scan
   information, and ultraviolet magnitude.
