Median Orbit Repeatability (see table below): 6.0 cm

This week, we add five new candidate global stations.  As with other sites,
these sites 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.)
