    keyword=Compton data from Oct 1st

    I've extracted some (very preliminary, very low statistics) data from the Compton tuning Eric did on Oct 1st (when we had low background rates). This data is from about 3 minutes of running with both laser on and laser off (laser right) at 20uA with the HV=-1650.

    I'm getting a beam polarization of 52.4+/-8% (with an arbitrarily large systematic error bar).
