Median Orbit Repeatability (see table below): 13.0 cm

Data from PRN29 appears mismodeled on days 066 and 067.  Although used in
the analyses of both days, we have chosen to remove its orbit solution from
the corresponding orbit products (jpl0895[56].sp3).

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 ALGO) used as reference clock days 063-066.
WARNING: Data from KELY, MAS1, NYAL excluded day 061.
WARNING: Data from DHLG, KELY, LONG, MAS1 excluded day 062.
WARNING: Data from KELY, LPGS, MAS1 excluded day 063.
WARNING: Data from CMBB, MAS1 excluded day 064.
WARNING: Data from GODE, LPGS, PAMA, UPAD excluded day 065.
WARNING: Data from HOPB excluded day 067.

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)
