Summary of OVRO Phase Monitor Data

OVRO, Caltech

I have analyzed the data from the OVRO phase monitor system. This
system is a copy of the one built by Colin Masson for Mauna
Kea. It monitors the 12.5GHz carrier from a geostationary satellite
DBS-1 using 100m baseline interferometer. The satellite is at an
elevation of 43deg. The main output is the RMS phase from the
interferometer over 5min intervals. We have archived data from
Dec. 1994 to Oct. 2003. Some 15% of the data is missing due to
equipment failures. The data was analyzed by accumulating the data
in two hour bins for each month giving 144 data sets per year. The
data sets from each year were then added together to produce the
final eight year average result.
