Median Orbit Repeatability (see table below): 13.0 cm

Beginning this week, we include data from three new Canadian sites.  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)
CHUR (Churchill, Manitoba)  -236438.7165  -3307616.8052  5430049.2562
FLIN (Flin Flon, Manitoba)  -766174.4504  -3611375.4113  5184056.4526
WHIT (Whitehorse, Yukon)   -2218337.9017  -2201205.1512  5543057.7560

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 CHIL, DAM2, DGAR, LPGS, MATE, ONSA excluded day 189.
WARNING: Data from DAM2, DGAR, LPGS, MATE, ONSA, TIDB excluded day 190.
WARNING: Data from DGAR, LPGS, MATE, ONSA, USC1, WLPS excluded day 191.
WARNING: Data from CASA, DGAR, NYAL, WETT, WLPS excluded day 192.
WARNING: Data from CASA, DAM2, DGAR, GOLD, USC1, WETT, WLPS excluded day 193.
WARNING: Data from CASA, DGAR, WETT excluded day 194.
WARNING: Data from DGAR excluded day 195.

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)
