Member Function Documentation

getMean() [1/2]

double getMean ( double  mom ) const

inline

Return dE/dx mean value for given cos(theta)

Parameters

mom	for const from momemtum value

Definition at line 81 of file CDCDedxMomentumCor.h.

    {
      if (std::abs(mom) > 10.0) return 0;
 
      // gains are stored at the center of the bins
      // find the bin center immediately preceding this value of mom
      double binsize = 10.0 / m_momcor.size();
      int bin = std::floor(mom / binsize);
 
      return m_momcor[bin];
    };
