Prototype at 2100V, 50/50 Ar/CO2
Trigger signals
Histograms of threshold-crossing bins in central bank of 16 straws, different thresholds (ignore the histo titles)
Histograms of ADC value=100 threshold-crossing bins in individual straws (search started at bin 160)
Same data after more normal analysis (Search forward to find pedestal+5sigma crossing, then backwards to find 4sigma and then 1sigma crossings)
Noise run (triggered on 20us pulser) ADC=100 crossing bins
