Function Documentation

A2a4Method()

std::vector< double > A2a4Method	(	TGraphErrors *	data,
		TGraphErrors *	z0,
		TGraphErrors *	z2,
		TGraphErrors *	z4 )

This method does a free fit of a_0, a_2, and a_4 to get the best possible result. The resulting parameters do not necessarily correspond to a meaningful physical result.

GetYError()

double GetYError	(	TGraphErrors *	graph,
		const double &	x )

general function to get the error of a graph at point x (takes the maximum of the errors of the bracketing points)

main()

int main	(	int	argc,
		char **	argv )

program to read in 2D matrices from AngularCorrelationHelper project and fit peaks to create angular correlation plots and to create chi-square plots
