Mean Orbit Repeatability (see table below): 18.9 cm

Beginning this week, we include data from several new stations.  As with most
stations, 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)

STRL (Sterling, Wash. D.C., USA):  1076000.7801  -4846966.3938   3990388.6871

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 ANKR, GOPE, KELY, KOSG, MAS1, NOTO, ONSA, TABL excluded day           330.
WARNING: Data from GOPE, HART, HERS, KELY, KOSG, LONG, MAS1, NOTO, ONSA, TABL,           VNDP excluded day 331.
WARNING: Data from KOSG, MAS1, MDVO, ONSA, SANT, TABL excluded day 332.
WARNING: Data from KOSG, MATE, SANT, SEY1, TABL, WETT, WHI1 excluded day 333.
WARNING: Data from CHIL, MATE, WETT, WHI1 excluded day 334.
WARNING: Data from CHIL, JOZE, KELY, MATE, MONP excluded day 335.
WARNING: Data from KELY, MAS1, SEY1 excluded day 336.
