    keyword=Target - EPR - 48.8%

    3:53am, EPR:

    photodiode DC -49mV, D2 ~ +/- 40uV
    3 longitudinal lasers on, during data taking (run#2009/21009), beam on
    gradient coils off,

    1st order fit:
    down: freq. shift = -53.55 KHz +/- 1.36 KHz, P = -48.91%+/- 1.24%
    up: freq. shift = 52.60 KHz +/- 1.40 KHz, P = 48.04%+/- 1.28%

    0th order fit:
    down: freq. shift = -53.26 KHz +/- 1.38 KHz, P = -48.64%+/- 1.26%
    up: freq. shift = 52.63 KHz +/- 1.53 KHz, P = 48.06%+/- 1.39%

    take the average of two fits, down flip as the target polarization
