We continue to deweight data from PRN10 this week.
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 PRN10 deweighted for the entire GPS week 887.
WARNING: Data from KELY, WTZR excluded day 005.
WARNING: Data from BRU1, DAV1, LHAS, ONSA, QUIN, SHK1 excluded day 006.
WARNING: Data from COCO, DAV1, LPGS, ONSA, SANT excluded day 007.
WARNING: Data from ONSA, SHK1, WETT excluded day 008.
WARNING: Data from BOGT, CAGL, CMBB, EBRE, ONSA, WETT excluded day 009.
WARNING: Data from CAGL, ONSA, WETT excluded day 010.
WARNING: Data from CAGL, DAV1, KELY, MDVO, WETT excluded day 011.
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)
