// Legacy35tZeroSuppressService.h

// David Adams
// November 2015
//
// Service wrapper for legacy 35-ton zero suppression.
// Code taken from run.cxx in dunetpc v04.29.02.
// Parameters:
//   AdcThreshold - threshold
//   TickRange - range
//   SuppressStickyBits - treat sticky bits as below threshold
// If a tick I has pedestal-corrected |ADC| > AdcThreshold, ticks
// [i-TickRange, i+TickRange] are retained.
// If tick I has sticky bits and has pedestal-corrected ADC < 64,
// it is treated as though its pedstal-corrected ADC is zero.
// If the gap between unsuppressed blocks is less that MinTickGap,
// then the bins in that gap are not suppressed. Edges (bins
// outside the tick range are treated as unsupressed.
