Function Documentation

fitRoo()

RooFitResult * fitRoo	(	TH1 *	hh,
		int	mr = 0,
		int	fr = 0,
		float	pmr = std::nanf("1"),
		float	pMr = std::nanf("1"),
		float	ymr = std::nanf("1"),
		float	yMr = std::nanf("1"),
		std::string	fnr = "YResonancesFit",
		int	vr = 0,
		int	cr = 0
	)

Implementation of the fit function.

Define a model function as sum of a quadratic background and three peak signals that can be chosen between breit wigner, gaussian, or t-student. Fit the histogram in input with the model function and print the result on the terminal. The data, the fitted model and its components are drawn on the canvas. On the canvas are also printed the cuts on tranverse momentum and rapidity, and the luminosity and CM energy as well. The result is saved in a pdf file with the name defined by parameter nfr. If the mode is set to "fit" an application with the canvas is displayed.

Parameters

hh	histogram to be fitted
fr	reference of fitFunction defined in main
pmr	recerence of ptm (minimum pt) defined in main
pMr	recerence of ptM (maximum pt) defined in main
ymr	recerence of ym (minimum rapidity) defined in main
yMr	recerence of yM (maximum rapidity) defined in main
nfr	recerence of nameFile defined in main
vr	reference of varaible verbose defined in main
cr	canvas flag: if on, do not display application

Returns

result of the fit

formatPtString()

TString formatPtString	(	float	pmr = std::nanf("1"),
		float	pMr = std::nanf("1")
	)

Formatting the string to be displayed on the canvas regarding the cuts made on pt.

If there are no custom cut, the default ones are printed.

Parameters

pmr	recerence of ptm (minimum pt) defined in main
pMr	recerence of ptM (maximum pt) defined in main

Returns

string formatted to print on the canvas

formatYString()

TString formatYString	(	float	ymr = std::nanf("1"),
		float	yMr = std::nanf("1")
	)

Formatting the string to be displayed on the canvas regarding the cuts made on y.

If there are no custom cut, the default ones are printed.

Parameters

ymr	recerence of ym (minimum rapidity) defined in main
yMr	recerence of yM (maximum rapidity) defined in main

Returns

string formatted to print on the canvas
