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
