Detailed Description

The base class of pulse reconstruction algorithms. All algorithms should inherit from this calss to be executed by a manager class, pulse_reco. Note that this class does not depend on the rest of the framework except for the use of constants. In order to reconstruct a pulse, all it requires is a std::vector<short> type object (i.e. raw waveform), waveform pedestal, and its standard deviation. All of these are to be provided by an executer. Reconstructed pulse parameters are stored in the pulse_param struct object.

All methods specified as "virtual" should be implemented by the inherit children class.

This class provides some basic std::vector calculation algorithms such as integral, derivative, max and min algorithms. Inherit children classes are encouraged to use these provided methods when possible.

bool pmtana::PMTPulseRecoBase::Derivative ( const std::vector< short > &  wf, std::vector< int32_t > &  diff, size_t  begin = 0, size_t  end = 0  ) const

protected

A method to compute derivative, which is a simple subtraction of previous ADC sample from each sample. The result is stored in the input "diff" reference vector which is int32_t type as a derivative could be negative.

Definition at line 117 of file PMTPulseRecoBase.cxx.

        diff.push_back(wf.at(index+1) - wf.at(index));

      return true;
    }

    return false;

  }

size_t pmtana::PMTPulseRecoBase::GetNPulse ( ) const

inline

A getter for the number of reconstructed pulses from the input waveform.

const pulse_param & pmtana::PMTPulseRecoBase::GetPulse

(

size_t

index = 0

)

const

A getter for the pulse_param struct object. Reconstruction algorithm may have more than one pulse reconstructed from an input waveform. Note you must, accordingly, provide an index key to specify which pulse_param object to be retrieved.

bool pmtana::PMTPulseRecoBase::Integral ( const std::vector< short > &  wf, double &  result, size_t  begin = 0, size_t  end = 0  ) const

protected

A method to integrate an waveform from index "begin" to the "end". The result is filled in "result" reference. If the "end" is default (=0), then "end" is set to the last index of the waveform.

size_t pmtana::PMTPulseRecoBase::Max ( const std::vector< short > &  wf, double &  result, size_t  begin = 0, size_t  end = 0  ) const

protected

A method to return the maximum value of ADC sample within the index from "begin" to "end". If the "end" is default (=0), then "end" is set to the last index of the waveform.
