Data from PRN08 were mismodeled on days 97.362 through 97.365. This
satellite's data have been excluded from the analyses of these days, and
subsequently deweighted for all other days this week.
Data from PRN14 were mismodeled on days 97.365 through 98.002, and have
been excluded from the analyses of these days. Data from PRN18 were also
mismodeled on day 97.365 and have been excluded from this day's analysis
only. Lastly, we continue to exlcude data from PRN13 this week.
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: MKEA (not NRC1) used as reference clock days 97.364-98.002.
WARNING: Data from PRN08 excluded days 97.362-97.365, deweighted days 98.001-98.003.
WARNING: Data from PRN13 excluded the entire GPS week 938.
WARNING: Data from PRN14 excluded days 97.365-98.002.
WARNING: Data from PRN18 excluded day 97.365.
WARNING: Data from MDVO, PIN1 excluded day 97.362.
WARNING: Data from CAGL, IISC, METS, WUHN excluded day 97.363.
WARNING: Data from METS, PIN1, QUIN excluded day 97.364.
WARNING: Data from PENC, SANT, SIO3 excluded day 97.365.
WARNING: Data from QUIN excluded day 98.002.
WARNING: Data from JPLM, NTUS excluded day 98.003.
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)
