According to the file nanu1995.mes obtained from the IGS CBIS, PRN21 was
unusable on day 181 for maintenance/repositioning.  Data from this satellite
did not meet our initial convergence criteria on this day and the following
day as well, and have been excluded from our analyses accordingly.

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 BRUS, FARB, GUAM, SPK1, ZIMM excluded on day 176.
WARNING: Data from GUAM, SPK1, TRAK, ZIMM excluded on day 177.
WARNING: Data from DAV1, SANT, TRAK excluded on day 178.
WARNING: Data from DAV1, MAC1, SPK1, TRAK, WHC1 excluded on day 179.
WARNING: Data from DAV1, EISL, FAIR, MAC1, METS, RCM5, SPK1, TAIW, THU1, TRAK,           WHC1, ZIMM excluded on day 180.
WARNING: Data from PRN04 excluded on days 181 and 182 due to a maneuver.

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)
