//
// Implementation of service to build ROIs in AdcChannelData using
// the same algorithm as in the original DUNE 35t module. An unpadded
// ROI starts for any signal above NSigmaStart sigma above the noise
// and continues until the level falls below NSigmaEnd sigma. The
// noise level sigma = sss.GetDeconNoise() where sss is the DUNE
// signal shaping service. Note that NSigmaEnd was fixed to 1.0 in
// the original code.
//
// The ROIs are then padded to include PadLow channels below and PadHigh
// channels above the unpadded region. Overlapping ROIs are then merged.
//
// The original code defines the upper value for an unpadded ROI to be one
// tick beyond the last tick above threshold unless it extends to the
// end of the sample array. Here the upper value is always set to be the
// last tick above threshold. one should be able to reproduce the old
// behavior by adding one to NSigmaEnd.
//
// The ROIs are recorded in in data.rois.
//
// Configuration:
//   LogLevel    - usual log level
//   NSigmaStart - Level in sigma at which an unpadded signal starts.
//   NSigmaEnd   - Level in sigma at which an unpadded signal ends.
//   PadLow      - Number of ticks to retain before signal above threshold.
//   PadHigh     - Number of ticks to retain after signal above threshold.
