Mean Orbit Repeatability (see table below): 16.6 cm

Beginning this week, we include data from DGAR (Diego Garcia).  As with most
stations, this site is given the opportunity to participate in the orbit and
clock solution as the global site distribution varies.  The following nominal
coordinates were assumed:

                       X (m)          Y (m)         Z (m)
          DGAR:    1916269.8296   6029977.4991  -801720.2539

According to the file nanu1996.mes obtained from the IGS CBIS, PRN20 is
unusable for an indefinite period beginning day 131.  Data from this satellite
were not available beginning day 132, hence its single-decimal precision in
the orbit repeatability table for day 131.

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 on days 127-131
WARNING: Data from MDO1, OHIG, STJO, TIBB, YAR1 excluded day 126.
WARNING: Data from LAMA, MATE, MDO1, STJO, TIBB, TRAK, VNDP, WETT, YAR1                  excluded day 127.
WARNING: Data from CMP9, LAMA, MATE, MDO1, SANT, STJO, TIBB, WETT excluded day           128.
WARNING: Data from COSO, MATE, MDO1, TIBB, ZIMM excluded day 129.
WARNING: Data from ASC1, GUAM, HBRK, KELY, MATE, SANT, TRAK, WTZR, ZWEN                  excluded day 130.
WARNING: Data from ASC1, CMBB, GUAM, LBCH, MATE, SANT, TIBB, WETT, WTZR                  excluded day 131.
WARNING: Data from DAM1, DAM2, DGAR, GUAM, KELY, LBCH, MATE, NYAL, STJO, TIBB,           WETT excluded day 132.

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)
