We continue to exclude data from PRN12 this week; data from this satellite
was inadvertently included on day 314.

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 (not ALGO) used as reference clock on day 313.
WARNING: PIE1 (not ALGO) used as reference clock on days 314 and 315.
WARNING: Data from PRN12 excluded on all days except day 314.
WARNING: Data from CLAR, GOLD, HOLC, HOLP, KOKB, KOSG, MATE, ONSA, SIO3, WHI1            excluded day 309.
WARNING: Data from CHIL, CLAR, DAV1, GOLD, HOLC, KOKB, KOSG, MATE excluded day           310.
WARNING: Data from CHIL, DAV1, KOKB, KOSG, LAMA, MDVO, NYAL, TABL, WETT                  excluded day 311.
WARNING: Data from BRAN, CHIL, DAV1, GRAZ, KOKB, LAMA, MDVO, SEY1, TABL, WHI1            excluded day 312.
WARNING: Data from ANKR, BRAN, DAV1, GRAZ, IRKT, KOKB, MATE, MDVO, MONP, SEY1,           SHAO excluded day 313.
