Median Orbit Repeatability (see table below): 13.0 cm
                           (excluding deweighted satellites)

According to the file nanu1996.mes obtained from the IGS CBIS, PRN24 was
unusable on days 351 and 352 for maintenance/repositioning.  Data from this
satellites did not meet our convergence criteria on either day, and have
been excluded from the analyses of both.

Similarly, PRN16 was unusable on days 354 and 355.  Data from this satellite
did meet our convergence criteria on both days; however, their inclusion
resulted in many outliers in our solutions.  These days were reanalyzed
excluding this satellite.

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 PRN24 excluded days 351 and 352 due to a maneuver.
WARNING: Data from PRN16 excluded days 354 and 355 due to a maneuver.
WARNING: Data from BRAN, DAM1, DAM2, HBRK, KRAK, WTZR excluded day 350.
WARNING: Data from BRAN, DAM2, DAV1, EBRE, HKLO, KRAK excluded day 351.
WARNING: Data from BRAN, CAS1, HBRK, HOLC, VCIO excluded day 352.
WARNING: Data from HVLK, KRAK excluded day 353.
WARNING: Data from CAS1, DAV1, JOZE, KRAK, YAR1 excluded day 354.
WARNING: Data from KRAK, XIAN excluded day 355.

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)
