We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).

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 USNO) used as reference clock day 285.
WARNING: NRC1 (not USNO) used as reference clock days 286-289.
WARNING: Data from KOUR, NYAL, TROM, USNA excluded day 283.
WARNING: Data from DGAR, KOUR, NYAL excluded day 284.
WARNING: Data from HERS, HNPT, KELY, KOUR, NYAL excluded day 285.
