Median Orbit Repeatability (see table below): 12.0 cm

Beginning this week, we have correctly applied the Block II/IIA and IIR offsets
of 1.023 and 0.000 m respectively.  Last week's sp3 files had erroneous clock
results for all satellites.

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 HARK excluded day 361.
WARNING: Data from COSO, DGAR, HARK excluded day 362.
WARNING: Data from HARK excluded day 363.
WARNING: Data from HARK, LPGS, NICO excluded day 364.
WARNING: Data from ASC1, HARK, NICO, WTZR excluded day 365.
WARNING: Data from NYAL excluded day 001.
WARNING: Data from ASC1, LPGS excluded day 002.

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)
