PRN12 has been rejected on days 310 and 311 (Nov 6, 7) because its eccentricity,from the broadcast ephemeris, exceeded our tolerance of 0.015.  These days
were processed prior to our increasing the tolerance to 0.020.

According to the file nanu1994.mes obtained from the IGS CBIS, PRN07 was
declared unusable for up to 12 hours beginning at 08:15 UT on day 314 (Nov 10)
for repositioning.  This satellite was excluded from our analyses on this day
and the following day as well.

WARNING: Data from HOB2, NYAL, TROM, WETT excluded on day 310 (Nov 6).
WARNING: Data from STJO, TAIW, USUD, WEST excluded on day 311 (Nov 7).
WARNING: Data from BOR1, STJO, TAIW, USUD, WEST excluded on day 312 (Nov 8).
WARNING: Data from NYAL, TROM excluded on days 313, 314 (Nov 9, 10).
WARNING: Data from KOSG excluded on day 315 (Nov 11).
WARNING: Data from MATE, WETT excluded on day 316 (Nov 12).
WARNING: Data from PRN07 excluded on days 314 and 315 (Nov 10, 11) due to a              maneuver.

In the following table, UT1R-UTC are the assumed nominal values from IERS
Bulletin-B predicts; estimated LODR values are also included.  See IGS Mail
Message 97 for details.
