private

◆ Exec()

void CbmTrdSetTracksPidLike::Exec ( Option_t * opt)
virtual

Task execution

loop over global tracks

get trd track

only trd tracks with mimimum 1 reconstructed point

Get the momentum from the first trd station

loop over all hits

calculate denominator for reasonable probabilities

normalize to 1

fill track values

◆ GetProbability()

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

Calculate probability for particle (with momentum) and dEdx

check for undefined dedx (dedx = -1. is sometimes passed in)

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
