Data from PRN08 were mismodeled on day 272 and have been excluded from this
day's analysis accordingly.
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: NRC1 (not USNO) used as reference clock day 273.
WARNING: Data from COCO, FORT, HARK, HOLC excluded day 270.
WARNING: Data from COCO, CRO1, HARK, LPGS, TROM excluded day 271.
WARNING: Data from PRN08, COCO, CRO1, HOB2, LPGS excluded day 272.
WARNING: Data from COCO, CRO1, HOB2 excluded day 273.
WARNING: Data from COCO, HOB2, LPGS excluded day 274.
WARNING: Data from COCO, HOB2, KERG, LHAS excluded day 275.
WARNING: Data from COCO, HOB2, KELY, LPGS excluded day 276.
