Similarly, PRN18 was unusable on days 202 and 203. Data from these satellites were excluded from our analyses on the appropriate days. 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.) WARNING: NLIB used as a reference clock on days 197-199.
