Data on days and sites as indicated in the following warnings have been
excluded from our analyses. Except for McMurdo (for which JPL's GPS Networks
and Operations Group informed us verbally of problems), such data were excluded
because they caused an excessive number of outliers in our solution. We are
investigating what in particular is "wrong" with the data, and would be
interested in sharing notes with other Analysis Centers, especially if they
find that they can include such data without difficulty.

WARNING: Data from GGAO and GRAZ have been excluded for the entire GPS week 718.
WARNING: Data from MCMU have been excluded for days 284 and 287 (Oct 11,14).
WARNING: Data from RCM4 have been excluded for day 289 (Oct 16).
