    keyword=EPR for Vertical Anti-parallel Pumping

    ************************************************************
    DATA ::: C:\HappyValentine\EPR\Data\EPR_AFP_20090120_1141
    Polarization = 64.7 %
    Calib Constant = 4.45 %/mV
    Cell = Brady
    Holding field = Vertical +
    Pumping Direction = Anti-Parallel
    ************************************************************

    The D2 light of vertical pumping is kind of weak, so we have to boost the
    RF quite a lot to get the EPR measurement done. Fortunately, the
    calibration constants from both pumping directions (parallel vs
    anti-parallel) are consistent in the level of 2%, therefore we can rely
    on parallel measurement only in the future.
