According to the file nanu1994.mes obtained from the IGS CBIS PRN29 was
declared unusable on day 258 (Sep 15) from 00:07 to 08:48 UT (no maneuver),
and there was little data from this satellite on this day.  Also, atypically
high clock repeatability was obtained for this satellite on this day.  Although
used in our processing, we have chosen to remove PRN29 from the sp3 orbit file
for day 258.

WARNING: Data from RCM5 excluded for the entire GPS week 766.
WARNING: Data from CAS1, DAV1, USUD excluded on day 254 (Sep 11).
WARNING: Data from CAS1, DAV1, QUIN excluded on day 256 (Sep 13).
WARNING: Data from MATE excluded on day 260 (Sep 17).
WARNING: Little data from PRN29 day 258 (Sep 15); excluded from jpl07664.sp3.

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.
