A clock reset of about 0.2 ms was detected for GPS19 at approximately 15:10 UT
on day 153.
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: FAIR (not ALGO) used as reference clock on day 158.
WARNING: Data from CSN1, LHAS, SANT, STL3 excluded day 152.
WARNING: Data from FLIN, KOUR, STL3, TSKB excluded day 153.
WARNING: Data from SNI1, STL3 excluded day 154.
WARNING: Data from ZWEN excluded day 155.
WARNING: Data from CASA, CMP9, TMGO, ZWEN excluded day 156.
WARNING: Data from CASA, KELY, MEDI, TMGO excluded day 157.
WARNING: Data from CASA, SNI1, TMGO excluded day 158.
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)
