keyword=Right arm gas cerenkov signals look very strange.The right arm gas cerenkov spectra are very unusual. We have protons, so these should mostly be pedestals. However, the ADC spectra are very spikey, and the TDC spectra make no sense. It looks to me like some kind of an ESPACE-level problem (possibly not updating the raw ADC value unless there is a TDC hit, or something like that). Note that the first 3 TDC channels did not have any hits. Figure 1=ADCs, figure 2=TDCs.
