GetProbability()

Double_t CbmTrdSetTracksPidLike::GetProbability ( Int_t  iType, Double_t  mom, Double_t  dedx  ) const

Calculate probability for particle (with momentum) and dEdx

useless protection

histogram has TRD momentum at inner point vs. dedx sinal [keV]

check for entries/ non-empty histograms

check for overlow

use bin width of last bin (correct in case of logarithmic, arbitrary binnning)

find bin depending on overflow in X,Y

interpolate empty bins or overflow bins
