    I remeasured the beam polarization for the same Wien angle 31.2 deg.
    The results is about the same as before: -75%.
    Somehow, during our measurement, the polarization (normalized to the
    target 5)
    dropped from 77.0 to 74.5%. First, I thought it was something to do with
    the Moller setup,
    as the thresholds or the position on the target, but have not found any
    Moller systematical dependence changing these parameters.
    It turned out the beam line was in the dispersive mode since the energy
    measurement in the morning, but I don't know if this matters.

    We will look more at the data and post the final results later.
