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 037-039 and 041-042.
WARNING: NRC1 (not USNO) used as reference clock day 040.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1048.
WARNING: Data from BJFS, GOL2, TID2, WTZT, PRN10 excluded day 037.
WARNING: Data from BJFS, CHAT, DAV1, GALA, GOL2, HOB2, KELY, MAC1, MCM4, NANO,         OHIG, REYK, RIOG, STR1, THTI, TID2, UCLU, USNO, WSLR, PRN26, PRN30              excluded day 038.
