Data from PRN13 were mismodeled this week, and have been excluded from
each day's analysis.  Additionally, we have chosen to deweight data from
PRN21 on day 305.

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: MKEA (not ALGO) used as reference clock day 299.
WARNING: PIE1 (not ALGO) used as reference clock day 305.
WARNING: Data from PRN13 excluded the entire GPS week 929.
WARNING: Data from PRN21 deweighted day 305.
WARNING: Data from CASA excluded day 299.
WARNING: Data from CASA, JOZE, KELY excluded day 300.
WARNING: Data from KSTU excluded day 302.
WARNING: Data from CASA, DHLG, GRAZ, SANT excluded day 303.
WARNING: Data from CASA excluded day 304.
WARNING: Data from CASA, CRO1, GOLD, MADR, TIDB excluded day 305.

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)
