Days 364 and 365 (Dec 30, 31) were processed after our updating of IERS 
Bulletin B nominal values.  This is manifested in the apparent discontinuity
in UT1R-UTC on day 364.

Due to potential problems, data from the following stations 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: Data from NYAL TROM      excluded on day 359 (94dec25).
WARNING: Data from MATE VILL WETT excluded on day 361 (94dec27).
WARNING: Data from WETT           excluded on day 362 (94dec28).
WARNING: Data from GRAZ MATE      excluded on day 364 (94dec30).
WARNING: Data from STJO WETT      excluded on day 365 (94dec31).

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.
