Median Orbit Repeatability (see table below): 10.0 cm

Beginning this week, we add several new candidate global stations.  As with
other sites, these stations are 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)

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 days 231-233.
WARNING: Data from PRN15, FORT, KOUR, TABL excluded day 227.
WARNING: Data from BRUS, FORT, NYAL excluded day 228.
WARNING: Data from AMC2, BRUS excluded day 229.
