According to the file nanu1997.mes obtained from the IGS CBIS, PRN30 was
unusable on days 085 and 086 for maintenance/repositioning. Data from this
satellite did not meet our initial convergence criteria on neither of these
days and have been excluded from our analyses accordingly.
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: PIE1 (not ALGO) used as reference clock days 087 and 088.
WARNING: Data from PRN30 excluded days 085 and 086 due to a maneuver.
WARNING: Data from BRU1, FMC2, HOB2, KELY, SANT, SHK1, STL3 excluded day 082.
WARNING: Data from SANT, XIAN excluded day 083.
WARNING: Data from COCO, GOLD, KELY, KERG, NYAL excluded day 084.
WARNING: Data from HFLK, KELY, XIAN excluded day 085.
WARNING: Data from KERG, YAR1, ZWEN excluded day 087.
WARNING: Data from BAHR, HART, KERG, LHAS, MALI, NYAL excluded day 088.
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)
