Data from PRN14 appear mismodeled on day 325.  We have chosen to deweight 
data from this satellite on this day.

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: PIE1 (not ALGO) used as reference clock days 322, 323, 325, and 326.
WARNING: MKEA (not ALGO) used as reference clock day 324.
WARNING: Data from PRN14 deweighted day 325.
WARNING: Data from METS, SNI1 excluded day 320.
WARNING: Data from ANKR, CHUR, KSTU, PENC, THU1 excluded day 321.
WARNING: Data from FORT, KSTU, SNI1 excluded day 322.
WARNING: Data from CASA, CAT1, KSTU, METS, PRDS, SNI1 excluded day 323.
WARNING: Data from CASA, CAT1, PRDS excluded day 324.
WARNING: Data from CASA, MAS1 excluded day 325.
WARNING: Data from MAS1 excluded day 326.

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)
