Abstract:
    A list of  900 radio  sources with  positional accuracies  better than
    0.5"  has been prepared from seventeen lists of radio source positions
    found in  the literature.  This compilation  includes all such sources
    south  of declination +48°  (the northern declination limit of the
    Compact Array of  the Australia  Telescope National  Facility).  Where
    available,  optical identifications,  optical magnitudes and redshifts
    are given as well as total-power flux densities.

History:
  * 09-Feb-1999: Prepared via OCR at CDS.
       From printed version, the 1950 position of 1348-34 was modified
       as RA=13 48 20.31 instead of RA=13 38 20.31
  * 11-Mar-2000: A check by H. Andernach showed that 1348-347 does not
       exist at all, and was in fact a confusion with 1438-347.
       This source was deleted, bringing the number of sources to 900.
