Data from PRN13 and PRN29 were mismodeled on days 139 and 143 respectively,
and have been excluded from the corresponding days' analyses appropriately.

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: NRC1 (not USNO) used as reference clock days 137-140.
WARNING: Data from BOR1, KSTU, NYA1 excluded day 137.
WARNING: Data from IRKT, KSTU excluded day 138.
WARNING: Data from PRN13, CLAR, IRKT excluded day 139.
WARNING: Data from AUCK, IISC, ONSA excluded day 140.
WARNING: Data from COCO, IISC, NYAL, ONSA excluded day 141.
WARNING: Data from COCO, ONSA, YAKZ excluded day 142.
WARNING: Data from PRN29, COCO excluded day 143.

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)
