Mean Orbit Repeatability (see table below): 16.8 cm

According to the file nanu1996.mes obtained from the IGS CBIS, PRN20 is
unusable for an indefinite period beginning day 142.  Although data from
this satellite were used on days 140-143, its formal errors exceeded our
criteria for day 143, and its solution was excluded from the sp3 orbit file
for that day (jpl08543.sp3).

Also, PRN25 was scheduled unusable on day 145 for maintenance/repositioning.
Data from this satellite did not meet our convergence criteria on this nor
the following day, and were excluded from both days' 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 BOR1, CMBB, DGAR, KELY, NYAL, POTS, TIBB, ZIMM excluded day           140.
WARNING: Data from BOR1, CMBB, KWJ1, POTS, STJO, TIBB, YAR1 excluded day 141.
WARNING: Data from CMP9, GOPE, MADR, QUIN, TIBB excluded day 142.
WARNING: Little data from PRN20 on day 143.
WARNING: Data from DGAR, KELY, PAMA, POTS, TIBB excluded day 143.
WARNING: Data from CMBB, JOZE, TIBB, VCIO excluded day 144.
WARNING: Data from PRN25, CMBB, DGAR, STRL excluded day 145.
WARNING: Data from PRN25, CLAR, DGAR, EISL, STRL excluded day 146.

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)
