Mean Orbit Repeatability (see table below): 21.6 cm

According to the file nanu1995.mes obtained from the IGS CBIS, PRN12 is 
unusable for an indefinite period beginning day 142 (May 22).  This satellite
was used in our processing through day 144 (May 24), and appears in our sp3
our products accordingly.  Additionally, PRN31 was unusable on day 143 (May 23)
due to maintenance/repositioning.  Data from this satellite did not meet our
initial convergence criteria for this day, as well as the following day (144), 
and were excluded from these days' analyses.

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, HOB2, KIT3, TAIW, YELL excluded on day 141.
WARNING: Data from GRAS, KIT3, MATE, TAIW, VILL excluded on day 142.
WARNING: Data from GRAS, KIT3, MATE, UPAD, USUD excluded on day 143.
WARNING: Data from PRN31 excluded on days 143 and 144  due to a maneuver.
WARNING: Data from HOB2, KIT3, MATE, USUD excluded on day 144.
WARNING: Data from BRUS, KIT3, MATE, TAIW excluded on day 145.
WARNING: Little or no data from PRN12 beginning day 145.
WARNING: Data from KIT3, TAIW, TSKB, USUD excluded on day 146.
WARNING: Data from KIT3, MAS1, MATE, TAIW, TSKB, USUD excluded on day 147.

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)
