Including BRMU caused atypically high clock repeatability values for day 156
Also, the inclusion of HARV on day 156 and HOBA on days 157 and 158 caused
excessive numbers of outliers in our solutions on these days. Data from MCMU
seemed to have an adverse effect in some of our analyses; we have excluded this
site for days 156-159.
In order to expedite processing, days 158-162 were analyzed with a well-
distributed subset of the global network consisting of no more than 25 sites.
The exclusion of other sites is not necessarily indicative of problems at those
stations.
We note usually large orbit repeatibilities for days 159-161, and an anomalous
change in LOD on day 160. These may be due to temporarily degraded orbit
accuracy associated with software changes related to the new GPS attitude model
which are currently under development.
WARNING: Data from BRMU and HARV excluded day 156 (Jun 5).
WARNING: Data from HOBA excluded day 157, 158 (Jun 6,7).
WARNING: Data from MCMU excluded days 156-159 (Jun 5-8).
