Mean Orbit Repeatability (see table below): 20.0 cm

Although used in some or all of our analyses, two satellites were removed from 
our orbit products due to possibly poorly modeled behavior.  The relevant 
exclusions are as follows:

PRN12: removed from jpl08322.sp3, jpl08325.sp3, jpl08326.sp3 (days 353,356,357)
PRN23: removed from jpl08324.sp3, jpl08325.sp3, jpl08326.sp3 (days 355-357)

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 LONG, MATE, TABL, WHI1 excluded day 351.

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)
