Median Orbit Repeatability (see table below): 12.0 cm

Data from PRN25 were mismodeled on days 083 and 084 and have been excluded
from these days' analyses accordingly.

According to IGS Mail No. 2152, equipment at CICE (Enseneda, Mexico) has
been relocated.  This week, we begin including the replacement site, CIC1,
as a global analysis candidate station, assuming the following nominal
coordinates:
                                X (m)          Y (m)          Z (m)
CIC1 (Ensenada, Mexico)   -2433176.9097  -4845045.0553   3348295.7635

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 080 and 081.
WARNING: FAIR (not USNO) used as reference clock day 083.
WARNING: Data from PRN18 excluded the entire GPS week 1002.
WARNING: Data from COCO, DGAR, GOLD, LPGS, QUIN, URUM excluded day 080.
WARNING: Data from COCO, HERS, KELY, KIT3, LPGS, QUIN excluded day 081.
WARNING: Data from COCO, GOLD, HARV, KIT3, LPGS excluded day 082.
WARNING: Data from PRN25, COCO, GOLD, KIT3, LPGS, TROM excluded day 083.
WARNING: Data from PRN25, COCO, LPGS, MADR, VESL excluded day 084.
WARNING: Data from BOR1, COCO, CRO1, GOLD, NYAL excluded day 085.
WARNING: Data from BOR1, BZRG, COCO, CRO1, EBRE, GOLD, LPGS excluded day 086.

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)
