Mean Orbit Repeatability (see table below): 14.1 cm

According to the file nanu1996.mes obtained from the IGS CBIS, PRN04 was
unusable on day 150 for maintenance/repositioning.  Data from this satellite
did not meet our convergence criteria on this nor the following day (151),
and have been excluded from these days' analyses accordingly.  Also, note that 
as data from PRN25 were not used in the analysis of day 146 (week 854, day 6),
there is only single-decimal precision for this satellite in our orbit
repeatability table on day 147.

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 DGAR, LAMA, POTS excluded day 147.
WARNING: Data from DGAR, KELY, MDVO, NYAL, POTS excluded day 148.
WARNING: Data from DGAR, KIRU, MATE, NOTO, POTS, SHAO, TAEJ, TIBB excluded day           149.
WARNING: Data from PRN20, ANKR, DGAR, KIRU, MATE, NYAL, POTS, TIBB excluded              day 150.
WARNING: Data from PRN20, DGAR, KIRU, MATE, POTS excluded day 151.
WARNING: Data from GOPE, MATE, NYAL, RCM5 excluded day 152.
WARNING: Data from DGAR, MATE excluded day 153.

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)
