Description:
    The Master List of Radio Sources (MSL) has been prepared by combining
    about thirty catalogues in a common format. Approcimately 25000
    listings are included for some 12000 separate sources.

Note (1): the used prefixes are detailed in file index.

Note (2): the frequency is unknown for the two records
          #26475.58 and #40580.58


Historical Notes:
  * The tape was received at CDS from Dr Robert S. Dixon (Ohio State
    University Radio Observatory) in 1978; an explicit request of
    not distributing tape copies of the MSL existed until 1995.
  * 16-Sep-1995 (version 'A'): a few modifications was performed at CDS:
    => removed last (dummy) record
    => corrected shifted columns in records
       #36489, 49515, 52808, 78129
    => Two unspecified values of the frequency exist in records
       #26475.58 and #40580.58
