According to IGS Mail Message 604, a modification was made to the antenna
at ALGO on day 139 (May 19).  Consequently, we have chosen to delete data
from this site on this day.  Also, FAIR was used as the reference clock on
this day and the previous day (day 138), due to a gap in ALGO data.

We continue to exclude data from NLIB; see jpl0748.sum for more information.
Additionally, IGS Mail Message 610 states that testing of the recevier at GODE
was done on day 140 (May 20).  We have deleted data from this site from this
day's analysis.

WARNING: Data from NLIB excluded for the entire GPS week 749.
WARNING: Data from ALGO excluded day 139 (May 19), antenna modification.
WARNING: FAIR (not ALGO) used as reference clock days 138 and 139 (May 18, 19).
WARNING: Data from GODE excluded day 140 (May 20), receiver testing.
