According to the file nanu1996.mes obtained from the IGS CBIS, PRN24 was
unusable on day 008 for maintenance/repositioning. This satellite did not
meet our initial convergence criteria on this nor the following day, and
its data were excluded from our analyses of both days.
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: Data from CHAT, KERG, MCM4, TID2, TIDB, TROM, YAR1 excluded day 007.
WARNING: Data from CHAT, HART, KERG, LAMA, MCM4, PERT, SIO3, TID2, TIDB, TROM,
YAR1 excluded day 008.
WARNING: Data from PRN24 excluded on days 008 and 009 due to a maneuver.
WARNING: Data from BRAN, CHAT, FAI2, KERG, MCM4, MONP, SIO3, TID2, TIDB, TROM,
VILL, YAR1 excluded day 009.
WARNING: Data from BRAN, MATE, SIO3, TABL, TRAK, VILL excluded day 010.
WARNING: Data from BRAN, CHIL, KOKB, MATE, NYAL, TRAK, TROM, VILL excluded day
011.
WARNING: Data from KOKB, MATE, TRAK excluded day 012.
WARNING: Data from FAIR, KOKB, MATE, PAMA, TRAK excluded day 013.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
