Peak length is # samples after the lower threshold crossing until the ADC value decreases by 2sigma over 2 samples, this is a measure of time over threshold in units of 8ns


50/50 gas, 2100V


Peak length vs first maximum in signal amplitude
No tilt
Tilted at 45 degrees


dE/dx calculated as full integration from low threshold crossing for next 700ns / track length parallel to endplates
No tilt
Tilted at 45 degrees
