According to the file nanu1994.mes obtained from the IGS CBIS, PRN27 was
declared unusable on day 235 (Aug 23) from 05:17 to 10:53 UT for maintenance
(no repositioning reported).  Similarly, PRN20 was reported unsuable from
04:30 on day 239 (Aug 27) to 15:13 UT on day 242.  These satellites have
been used in our processing, but removed from the corresponding sp3 orbit
products.

In order to expedite processing, some days were analyzed using a well-
distributed subset of the global network consisting of no more than 31
ground stations.

WARNING: Little data from PRN27 day 235 (Aug 23); excluded from jpl07632.sp3.
WARNING: Little data from PRN20 day 239 (Aug 27); excluded from jpl07636.sp3.
WARNING: Data from ALGO, RCM5 excluded days 237, 238. FAIR used as reference             clock on these days only.
WARNING: Data from MATE excluded for the entire GPS week 763.
WARNING: Data from PRN01 excluded day 238; not well-modeled.

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.
