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 days 256 and 260.
WARNING: FORT (not USNO) used as reference clock days 257 and 258.
WARNING: Data from PRN15 excluded days 257 through 261.
WARNING: Data from CASA, JAB1, MAC1, PVEP excluded day 255.
WARNING: Data from BRUS, CASA, MAC1, SUTH excluded day 256.
WARNING: Data from CASA, MAC1 excluded day 257.
WARNING: Data from BLYT, CASA, HARV, HERS, NYAL, TROM, VILL excluded day 258.
WARNING: Data from BLYT, CASA, GODE excluded day 259.
