    keyword=Rotate holding field to 270 deg.

    Nilanga (the R.C. ) calls and tells us to rotate to transverse holding field, to
    improve the pumping efficiency, since the recent EPR measurement gave
    such a low polarization.
    - move target to 3He cell position
    - turn off lasers 5,6,7
    - rotate from 0 degrees to 270 degrees
    - turn on lasers 1,2,3


    ious fits of NMR measurements done without the gradient field on. I found the average to be 67 mG. With that parameter set, the gradient field is consistently fit to be 11.6 mG/cm in the z-direction at 6.85 Amps.
