Mean Orbit Repeatability (see table below): 20.9 cm

There were little or no data for PRN12 on days 169-171.  Additionally, this 
satellite did not meet our initial convergence criteria on days 174 and 175, 
Hence, it is absent from the corresponding orbit repeatability table columns
and sp3 orbit products.

According to the file nanu1995.mes obtained from the IGS CBIS, PRN04 was
unusable on day 173 for maintenance/repositioning.  Data from this satellite 
did not meet our initial convergence criteria on days 172-174, 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: Little or no data from PRN12 on days 169-171.  Data from this                   satellite excluded on days 174 and 175 also.
WARNING: Data from BRIB, CHIL, DRAO, GUAM, MATE, MONP, SHAO, SPK1, TROM, TAIW,           VNDP excluded on day 169.
WARNING: Data from CHIL, DRAO, GUAM, MADR, MATE, MONP, SHAO, SPK1, TROM, TAIW,           VNDP excluded on day 170.
WARNING: Data from CHIL, MADR, SPK1, TAIW, VNDP excluded on day 171.
WARNING: Data from PRN04 excluded on days 172-174 due to a maneuver.
WARNING: Data from CHIL, FARB, HART, KOKB, MADR, SPK1, TAIW excluded on day              172.
WARNING: Data from ALGO, CMBB, FARB, HART, KOKB, SPK1, TAIW excluded on day              173.  NLIB used as a reference clock on this day.
WARNING: Data from ALGO, CMBB, FARB, HART, KOKB, SPK1 excluded on day 174. NLIB          used as a reference clock on this day.
WARNING: Data from CMBB, BRUS, FARB, GUAM, ZIMM excluded on day 175.

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)
