Subject: NOAA's Earth Orientation Parameter files.
Dear Colleagues,
Beginning April 1, 1997, NOAA inadvertently began misapplying the
a priori polar motion values released by the United States Naval
Observatory. This resulted in incorrect computed values in NOAA's
Earth Orientation Parameter (EOP) files (i.e., ngs08997.erp,
ngs09007.erp, ngs09017.erp, ngs09027.erp, and ngs09037.erp) and
NOAA's Sinex files (i.e., ngs08997.snx, ngs09007.snx, ngs09017.snx,
ngs09027.snx, and ngs09037.snx).
The daily orbit files (i.e., ngsWWWWn.sp3) were not affected.
The EOP files and the Sinex files have been corrected (16 May, 1997)
and have been resubmitted to CDDIS.
NOAA apologizes for any inconvenience.
Sincerely,
William Kass
