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: ALGO (not USNO) used as reference clock days 1999.360 - 1999.363.
WARNING: NRC1 (not USNO) used as reference clock days 1999.364 and 1999.365.
WARNING: FORT (not USNO) used as reference clock day 2000.001.
WARNING: Data from PRN11/GPS46 and PRN15 excluded the entire GPS week 1042.
WARNING: Data from PRN14 and PRN29 excluded days 1999.362 - 2000.001.
WARNING: Data from PRN18 excluded days 1999.361, .362, and .365.
WARNING: Data from AZU1, KOKB, MAC1, PETP, TID2, WTZR, ZIMM excluded day 360.
