According to the file nanu1995.mes obtained from the IGS CBIS, PRN28 was
unusable from 04:30 UT on day 066 (Mar 7) until 02:41 UT on day 067 (Mar 8).
Although included in our processing for day 066, this satellite's formal
errors were such that they were excluded from this day's IGS orbit file
(jpl07912.sp3), and the orbit repeatability tables as well.

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 GRAZ, JOZE, LAMA, MATE, PERT excluded on day 064 (Mar 5).
WARNING: Data from WETT excluded on day 065 (Mar 6).
WARNING: Data from MDO1, TMGO excluded on day 066 (Mar 7).
WARNING: Data from GRAZ, MATE excluded on day 069 (Mar 10).
WARNING: Data from GRAZ, LAMA, MATE, METS excluded on day 070 (Mar 11).

In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column.  See IGS Report No. 1498 (jpl07827.sum)
