[esa-t474] Re: Run 1421

[Michael Albrecht]

I've been able to access a few of the data files and pull out the 
interferometry data.
Here's a link to some plots I've generated from Run 1421 ( a 20k event 
stability run), both long term and zoom-in plots of each end.

It appears there is a 600 nm drift in the mean value of BPM 3, a 500nm drift 
for BPM 5, and just a 25nm drift in the mean value of BPM 4 over the course 
of the run.
The RMS values, on the other hand, stay fairly constant.
