    Entry number 65559

    keyword=Target - EPR - 38.8%

    6:55am: EPR: during data taking run number 1936/20936

    Target position: pol 3he cell
    gradient coil current: T = 5.00A, L = -2.00A

    1st order fit:
    down: freq. shift = -46.84 KHz +/- 2.51 KHz, P = -38.91%+/- 2.08%
    up: freq. shift = 46.56 KHz +/- 2.50 KHz, P = 38.67%+/- 2.07%

    0th order fit:
    down: freq. shift = -46.65 KHz +/- 2.43 KHz, P = -38.75%+/- 2.02%
    up: freq. shift = 46.49 KHz +/- 2.55 KHz, P = 38.61%+/- 2.12%

    Note:
    I am using the average of 0th and 1st order fit of down flips in the title.

    Before sweeps I checked the EEL lab logbook again and set both gains to be 1 turn
    (based on Lab data) since the current setting cannot be worse anyway. Then with Mod source 1.5Vpp (suggested by Wolfgang yesterday) I did one good sweep. I
    am confident about the numbers quoted above.
