Median Orbit Repeatability (see table below): 9.0 cm

A few satellites were mismodeled this week; these were PRN19 on day 326, PRN29
on day 329, and PRN06 and PRN24 on day 330.  Data from these satellites have
been excluded from the corresponding days appropriately.

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 day 327.
WARNING: Data from PRN19, ASC1, COCO, CRO1, HARK, HOLB, NYAL excluded day 326.
WARNING: Data from COCO, CRO1, HARK, HOLB, KERG excluded day 327.
WARNING: Data from COCO, CRO1, HARK, HOLB excluded day 328.
WARNING: Data from PRN29, COCO, FORT, HARK, HOLB, TRO1 excluded day 329.
WARNING: Data from PRN06, PRN24, COCO, FORT, HARK, HOLB, LPGS excluded day 330.
WARNING: Data from COCO, FORT, HARK, HOLB, LPGS excluded day 331.
WARNING: Data from COCO, HARK, HOLB, LPGS excluded day 332.

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)
