Median Orbit Repeatability (see table below): 7.0 cm

This week, we add three 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)

TWTF (Taoyuan, Rep. of China)    -2994428.0896    4951309.3583    2674496.8973

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 AOA1, CARR, DARW, JAB1, KUNM, LBCH, WTZA, YEBE excluded day           315.
WARNING: Data from AOA1, BJFS, DARW, IRKT, JAB1, KELY, LBCH, NLIB, YEBE                  excluded day 316.
