    keyword=Longitudinal Quater Wave Plate Calibration

    all 4 longitudinal quater-wave plates are re-calibrated to minimize laser
    absorption (~= higher laser polarization). The result is

    Motor 1426 = plate #5 on S wave upstream facing upstream -> 113 Degree
    Motor 1423 = plate #6 on S wave downstream facing upstream -> 130 Degree

    plate #15 on P wave upstream facing downstream -> -8 Degree
    plate #16 on P wave downstream facing downstream -> 1 Degree
