Data from PRN14 were mismodeled on day 156, and have been excluded from our
analyses accordingly.

A large clock discontinuity (reset) of about 385 microseconds was detected
for PRN19 at approximately 04:35 on day 156.

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 IISC excluded day 151.
WARNING: Data from WUHN excluded day 152.
WARNING: Data from NYAL excluded day 154.
WARNING: Data from NYAL, WES2 excluded day 155.
WARNING: Data from PRN14, NYAL excluded day 156.

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)
