Data from cosmics with 50/50 gas, 2100V
Fit attempt 1
Use pedestal before peak, max peak amplitude, end of peak - this is the first sample with contents > 20 less than its neighbor, starting with the last sample and working forwards. Function fitted to many events for range end-of-peak to final sample was pedestal + 0.14 * maxamp * exp(-0.0056*(x-endpeak))
