    keyword=fraction of anomolous T2,T4 (not too bad)

    Checked 1 Million events of run 1410. Results below are
    TDC spectra on paddles 2 and 3 of S1 plane where rates
    are maximum on both spectrometers. They are typical of
    the paddles. The cuts require that the pattern is "S-Ray" logic,
    hence the T2 and T4 are anomolous. One can see they mostly
    have strange timing. The size (or order of magnitude) of the effect is
    0.16% for E-arm and 1.1% (worse) for H-arm. The effect seems
    to have been stable since yesterday, and is reasonably small.
