    keyword=Holding field rotated from 270 to 0, NMR: 40.5% , EPR: 38.8%

    10:10 Beam off, lasers off, target moved to BeO position
    10:25 laser half wave plate moved out
    10:28 rotate holding field from 270 degree to 0 degree.
    10:35 target moved to pick-up coil position
    10:36 turn on longitudinal lasers #5,6,7
    10:52 NMR : P=40.5%
    Target@pick up coil position, holding field@0 degree, beam off, gradient coil off.
    11:02 EPR measurement: P=38.8%
    1st order fitting only
    freq1: -42.79 kHz +/- 1.74 kHz | Polarisation: -39.08 % +/- 1.59 %
    freq2: 42.14 kHz +/- 1.71 kHz | Polarisation: 38.49 % +/- 1.56 %

    Comment: holding field still drifting during the NMR and EPR measurement
