We continue to exclude data from WEST; see IGS Mail Message 585 for details.
Also, the inclusion of NLIB caused atypically high clock repeatabilities for
day 121 (May 1), although we are not sure why.  In addition, the inclusion of
various sites caused an excessive number of outliers in several analyses this
week.  These are: MCMU on day 123 (May 3), HOBA and NLIB on day 125 (May 5),
and from STJO on day 126 (May 6).  We have deleted data from these sites on
the corresponding days.

According to the file nanu1994.mes obtained from the IGS CBIS, PRN18/GPS18
was unusable from 13:03 to 21:12 UT on day 126 due to repositioning.  This
satellite was excluded from our processing on this day, and the following
day as well.

WARNING: Data from WEST excluded for the entire GPS week 747.
WARNING: Data from NLIB excluded day 121.  Clock and orbit repeatability for             Sat, Apr 30 in jpl07467.sum did not reflect the removal of this site            from the results for Sun, May 1, week 747. 
WARNING: Data from MCMU excluded day 123 (May 3).
WARNING: Data from HOBA and NLIB excluded day 125 (May 5).
WARNING: Data from STJO excluded day 126 (May 6).
WARNING: PRN18 not used days 126 and 127 (May 6, 7) due to a maneuver.
