Member Function Documentation

unsigned int APReweight::GetBin ( double  value  )  const

Get bin number that corresponds to a given value.

APWeightEntry * APReweight::GetBinWeight ( unsigned int  bin  )  const

Get Weight entry for a given bin number.

TH1D * APReweight::GetDenominatorHist (  )  const

Get original denominator histogram.

TH1D * APReweight::GetNumeratorHist (  )  const

Get original numerator histogram.

double APReweight::GetSampleScale (  )  const
