Median Orbit Repeatability (see table below): 15.0 cm

Per IGSMail numbers 2071 and 2075, we continue to exclude data data from
the following sites:

   AREQ ASC1 BARB BOGT BRAZ COCO CRO1 DGAR FORT GALA GUAM IISC
   KOKB KOUR KWJ1 MALI MKEA MOIN NOUM NTUS RIOP SEY1 THTI

Data from PRN19 and PRN21 were mismodeled on days 066 and 071 respectively,
and have been excluded from the corresponding day's analysis accordingly.

Solutions for day 073 (week 1001 day 0, 99mar14) are not available at this
time.  As such, orbit overlaps for day 072 in the repeatability table below 
represent comparisons with the previous day (071) only.

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 070.
WARNING: Data from PRN19, KELY, LPGS, UCLP, VENE excluded day 066.
WARNING: Data from KSTU, LPGS, UCLP excluded day 067.
WARNING: Data from COCO, LPGS excluded day 068.
WARNING: Data from COCO, KSTU, LPGS, POTS excluded day 069.
WARNING: Data from LPGS, POTS, URUM excluded day 070.
WARNING: Data from PRN21, LPGS, POTS, URUM excluded day 071.
WARNING: Data from LPGS, URUM excluded day 072.

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)
