Median Orbit Repeatability (see table below): 11.0 cm
Data from PRN14 did not meet our initial orbit convergence criteria on days
223 and 224, and have been excluded from the analyses of both days accordingly.
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: FAIR (not ALGO) used as reference clock days 227 and 228.
WARNING: Data from COCO, LAMA, QUIN, ZWEN excluded day 222.
WARNING: Data from COCO, SANT, TAIW, ZWEN excluded day 223.
WARNING: Data from DGAR, QUIN, TAIW, ZWEN excluded day 224.
WARNING: Data from TAIW, VCIO excluded day 225.
WARNING: Data from POTM, VCIO excluded day 226.
WARNING: Data from AUCK, AZU1, QUIN, SNI1, TID2 excluded day 227.
WARNING: Data from MONP, PIE1 excluded day 228.
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)
