A large clock discontinuity (reset) of about 541 microseconds was detected
for PRN09 at approximately 17:45 on day 201.
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: DRAO (not USNO) used as reference clock days 198 and 202-204.
WARNING: ALGO (not USNO) used as reference clock days 200 and 201.
WARNING: Data from AUCK, HOLC, LBCH, TRAB, WTZT excluded day 198.
WARNING: Data from HOLC, INEG, JAMA, KELY, LBCH, RAMO, WTZT excluded day 199.
WARNING: Data from DGAR, HOLC, JAMA, LBCH, THU1 excluded day 200.
WARNING: Data from HOLC, LBCH, TEGU excluded day 201.
WARNING: Data from DGAR, LBCH excluded day 202.
WARNING: Data from NOUM excluded day 204.
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)
