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.

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
