Member Function Documentation

Convert()

std::unique_ptr< TH1F > Centrality::BordersFinder2D::Convert

(

)

Converts 2D histo to 1D. Transformation is done moving along fit to 2D distribution and counting number of entries perpendicular to it.

Returns

pointer to 1D histo

FindIntegral()

double Centrality::BordersFinder2D::FindIntegral	(	const std::array< double, 2 > &	norm1,
		const std::array< double, 2 > &	norm2 )

Find number of entries between lines norm1 and norm2

Parameters

norm1	first line parametrization y=a+bx
norm2	seconsd line parametrization

Returns

number of entries (integral)

FindNorm()

std::array< double, 2 > Centrality::BordersFinder2D::FindNorm	(	const std::vector< double > &	par,
		double	x )

Parameters

par	parameters of polinomial function
x	argument

Returns

a0 and a1 parameters y = a0 + a1 * x

polN()

static double Centrality::BordersFinder2D::polN ( const std::vector< double > & par, double x )

inlinestatic

Parameters

par	parameters of polinom
x	argument
N	order

Returns
