Detailed Description

Class that implements the efficiency description across the signal Dalitz plot.

Class that defines the efficiency model variation across the signal Dalitz plot. The method is based in a predetermined two-dimensional histogram to characterize the phase space acceptance. The efficiency variation is defined in terms of x = m_13^2, y = m_23^2 for the Dalitz plot (default) or x = m', y = theta' for the square Dalitz plot

◆ addEffHisto() [1/2]

void LauEffModel::addEffHisto	(	const TH2 *	effHisto,
		Bool_t	useInterpolation = `kTRUE`,
