    keyword=Target - EPR - 39.6%

    0:10am, EPR, laser #6, gradient coil current transverse 5.0A, longitudinal -3.0A.
    Target @ polarized 3he cell, during data taking.

    1st order fit:
    frequency shift down: -47.70 +/- 1.84 KHz
    frequency shift up: 47.03 +/- 1.88 KHz
    Polarization down: -39.61% +/- 1.53%
    Polarization up: 39.06% +/- 1.56%

    0th order fit:
    frequency shift down: -47.45 +/- 2.14 KHz
    frequency shift up: 46.91 +/- 1.92 KHz
    Polarization down: -39.41% +/- 1.78%
    Polarization up: 38.96% +/- 1.59%

    Since polarization is steadily going up, will stay @ 5.0/-3.0A for 4 more hours.

    killmazing:
    IF the next EPR measurement shows it reaches maximum
    -> increase transverse coil current by 1.0A;
    We expect the maximum (when mazing is completely gone) to be comparable with
    in beam maximum 43% at transverse direction;

    ELSE IF the next EPR shows
    it is still going up -> wait for 4 more hours -> goto killmazing.
