    keyword=NMR Cross Calibration for transverse pumping

    An NMR Cross calibration has been performed to obtain calibration
    constant between production NMR and water calibration.

    * Cell: Brady
    * Holding Field: Transverse +
    * Pumping Direction: -
    * NMR RF Coil: Vertical
    * NMR Pumping Chamber Pickup Coil: Longitudinal
    * Oven Temperature: 230C

    Time Line
    ========================
    12:20 NMR Freq Sweep @ Trans
    Data directory : NMR_Freq_He_20090217_122022
    12:21 Field -> Long. +; Target -> Pick up
    12:25 NMR Field Sweep @ Long and Pickup
    Data directory : NMR_He_20090217_122551
    12:26 Field -> Trans -; Target -> he3
    12:33 NMR Freq Sweep w/ wrong pickup cable (two AFP loss ~ 1%)
    12:34 NMR Freq Sweep @ Trans
    Data directory : NMR_Freq_He_20090217_123430

    During the field sweep, the downstream target chamber pickup coil looked
    wierd. I will check it.
