We have been monitoring the baseline solutions for the stations in the
Los Angeles Basin (DGGA). We find very poor results for the stations
at Oat Mountain (OATT) and Mt. Wilson (WLSN), and excellent results
for all other stations. Can anyone confirm this observation, and shed
light on the problem? I believe that it is due to severe multipath
or radio interference.

The symptoms can also be viewed on the IGPP Mosaic:

Click PGGA
Click SCIGN Map
Click on Palos Verdes (for example)
Click on other sites to see baseline time series.

Similar but less severe problems can be seen in the solutions
for Parkfield (CARR).
