    keyword=Target NMR: 45.6% EPR: 46.2%


    16:27 beam off
    16:30 move target to pick up coil position
    NMR with 3 longitudinal lasers on, P=45.6%
    16:35 EPR P=46.2%
    target@pick up coil position, holding field@0 degree. gradient coil off.
    EPR 0th order fit:
    freq1: -49.74 kHz +/- 1.09 kHz | Polarisation: 46.51 % +/- 1.02 %
    freq2: 49.46 kHz +/- 1.23 kHz | Polarisation: 46.25 % +/- 1.15 %
    1st order fit:
    freq1: -49.44 kHz +/- 1.09 kHz | Polarisation: 46.23 % +/- 1.02 %
    freq2: 49.11 kHz +/- 1.27 kHz | Polarisation: 45.92 % +/- 1.19 %

    comments: Vmod=0.85Vpp, Time(wait/sweep)=16/6second, shape is not good. Should use 24/8 instead.

    16:43 turn off 3 longitudinal lasers ,and rotate holding field from 0 to 270 degree
    16:50 target@270 degree, turn on transverse lasers(#1,2,4) and ready for beam
