    keyword=Shower block 15.

    Left arm shower counter block #15 has generally been giving no signal in the detector replays of 20-50k events. It is in the corner of the acceptance, where there are basically no real signals, so it is most likely a problem with the ADC threshold for sparsification. This should be checked when there is a run without pedestal sparsification, or after the next pedestal run.
