    keyword=Target - EPR - 48.1% ?

    5:20am, EPR performed (after NMR)

    3 longitudinal lasers (#5, #6, #7) on;
    beam off;
    target position: pol 3he cell;
    photodiode signal -52mV, D2 signal ~ +/- 40uV;
    EPR RF amplitude: 15.0V, frequency 11.71 MHz;
    Mod source amplitude: 0.7 Vpp;
    sweeping/waiting time = 6 / 16 sec;
    resonance frequency ~ 11.79 MHz;
    calibration constant: 0.913237 (%/KHz).

    1st order fit:
    down: freq. shift = -52.91 KHz +/- 1.15 KHz, P = -48.32%+/- 1.05%
    up: freq. shift = 51.50 KHz +/- 1.60 KHz, P = 47.04%+/- 1.46%

    0th order fit:
    down: freq. shift = -52.50 KHz +/- 1.09 KHz, P = -47.95%+/- 0.99%
    up: freq. shift = 51.71 KHz +/- 1.09 KHz, P = 47.23%+/- 0.99%

    I put the average of these two fits in the entry title.
