Median Orbit Repeatability (see table below): 15.0 cm

Data from PRN10 appeared to be mismodeled on day 246, as evidenced by an
anomalous LODR estimate on this day.  We have chosen to re-analyze this day,
excluding this satellite from the processing.

According to the file nanu1996.mes obtained from the IGS CBIS, PRN22 was
unusable on day 250 for mantainence/repositioning.  Data from this satellite
did not meet our convergence criteria on this nor the previous day, and
have been excluded from both day's analyses.

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 CMP9, DGAR, IISC, MAS1 excluded day 245.
WARNING: Data from PRN10, DAM2, DGAR, KRAK, SANT excluded day 246.
WARNING: Data from KOUR excluded day 247.
WARNING: Data from CMBB, CRO1, DAM2, DGAR, IRKT excluded day 248.
WARNING: Data from PRN22 excluded on days 249 and 250 due to a maneuver.
WARNING: Data from CHAB, DGAR, GODE, ONSA, SNI1, WETT excluded day 249.
WARNING: Data from DGAR, FMC2, ONSA, WETT excluded day 250.
WARNING: Data from TAEJ, WETT excluded day 251.

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)
