Data from PRN29 and PRN18 were mismodeled on days 257 and 261 respectively.
Data from these satellites have been excluded from the processing of the
corresponding days appropriately.
A large clock discontinuity (reset) of about 48 microseconds was detected
for PRN04 at approximately 15:25 on day 257.
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 USNO) used as reference clock days 258 and 259.
WARNING: Data from COCO, NYAL excluded day 256.
WARNING: Data from PRN29, COCO, HOB2, KELY, NSSP, TROM excluded day 257.
WARNING: Data from BARB, COCO excluded day 258.
WARNING: Data from COCO, CRO1 excluded day 259.
WARNING: Data from COCO, CRO1, HOB2, MAG0 excluded day 260.
WARNING: Data from PRN18, COCO, CRO1, DAV1, HOB2 excluded day 261.
WARNING: Data from COCO, CRO1, DAV1, HOB2 excluded day 262.
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)
