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 053-055 and 057.
WARNING: NRC1 (not USNO) used as reference clock day 056.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1050.
WARNING: Data from DARW, GODE, GOL2, KUNM, RIOP, TID2, WHIT, PRN06, PRN08                excluded day 051.
WARNING: Data from BARB, DARW, GOL2, KUNM, RIOP, TID2, PRN06, PRN08 excluded             day 052.
