geographical reasons, they may not have been used in any case.)
WARNING: ALGO (not NRC1) used as reference clock on day 088.
WARNING: USNO (not NRC1) used as reference clock on days 089 through 091.
WARNING: TID2 (not NRC1) used as reference clock on day 092.
WARNING: Data from PRN08 were deweighted for the entire week 951.
WARNING: Data from PRN13 were deweighted day 088 only.
WARNING: Data from LPGS excluded day 088.
WARNING: Data from LPGS, MADR, SANT excluded day 089.
WARNING: Data from LPGS, MADR excluded day 090.
WARNING: Data from BILL, LPGS excluded day 091.
WARNING: Data from LPGS excluded day 092.
