normalizeStep()

void Rivet::Cutflows::normalizeStep ( const std::string & edge, const double norm )

inline

Scale the cutflow weights so that the weight count after cut edge is norm

Note

Consider each sub-histogram separately when calculating the integral.

Referenced by normalizeFirst().

reset()

void Rivet::Cutflows::reset ( )

inlinenoexcept

Reset the histogram.

Keep the binning but set all bin contents and related quantities to zero
