A clock discontinuity (reset) of about 37 microseconds was detected for
PRN08 at approximately 15:15 on day 016.

Due to potential problems, data from stations mentioned below 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.)
