2009.11.22 - Measurement Repeatability

How well can we repeat measurements? Start with taking 20 orbits (124073:124092, 11/21/09 data), and look at the standard deviation of those orbits. Only consider cBPM II's for now.

Repeat for disperson, using 7 consecutive measurements (eta.900:906, 11/21/09 data):

Repeat dispersion test, with 11 mesurements (eta.907:917, 11/22/09 data):

Now correct the coupling and take several consecutive phase/coupling measurements (phase.8338:8356, 11/22/09 data). Analyze data in a similar fashion:

Fit each phase/coupling measurement using the following procedure:

Plot the mean fitted BPM tilt at each BPM, and the standard deviation as error bars:
