Median Orbit Repeatability (see table below): 11.0 cm

Beginning this week, we include data from AZU1 (Azusa CA, USA).  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)
          AZU1:   -2472982.3618  -4671357.9847  3558120.4291

Due to several processing anomalies, days 214 and 215 were processed using
a global network of only 28 stations.

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 DGAR excluded day 210.
WARNING: Data from DGAR, TROM, TSKB excluded day 211.
WARNING: Data from CHIL, DGAR, KELY, NYAL, TABL, TROM excluded day 212.
WARNING: Data from DGAR, HOLC excluded day 213.
WARNING: Data from DGAR, KOKB, LEEP, METS, WETT excluded day 214.
WARNING: Data from CHIL, DGAR, SANT, WETT, WINT excluded day 215.
WARNING: Data from DGAR, GUAM, KIT3, WETT excluded day 216.

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)
