    keyword=EPR/NMR measurement

    3:50 turn off transverse lasers
    move target to pickup coil position
    rotate holding field from 270 degree to 0 degree
    holding field: Trans=-0.0856A,Long=-7.0600A
    gradient coil : trans= 5.00A ,long=-2.0A
    3:55 NMR measurement
    the shape is not good (noise?)
    4:20 two epr measurement failed, the 3rd succeeded.
    Long=-7.040A at the time of the 1st EPR try, target at pickup coil position
    Long=-7.030A at the time of the 1st EPR try, target at pickup coil position
    Long=-7.020A at the time of the 3rd EPR try. target at beam line position

    fitting result:
    0 order fitting
    down: -49.7+/-3.8 KHz 41.3+/-3.2%
    up: 47.5+/-4.2 KHz 39.4 +/- 3.5%
    1 order fitting
    down: -47.1+/-3.9 KHz 39.1+/- 3.2%
    up: 45.7+/-3.7 KHz 38.0+/- 3.1%

    4:30 turn off laser #6
    rotate holding field back to 0 degree
    turn on 3 transverse lasers
