    keyword=Compton electron Run 21246 hit pattern

    Position 30 mm from the beam, thresold 22.
    2 plane coincidence, or width of 4.
    Plan B,C and D seems to have reasonable distribution.
    Strips are a bit noisy around strip 19.
    Big noise starting at strip 64 in all 3 planes.
    Plane A still gets hits while disabled. Only first 96 strips enabled.
    Some hits beyond channel 96. Will check efficiency when standard decoding is done
