◆ estimateNeutronFlux()

std::vector< std::vector< double > > STOFFluxAnalysis::estimateNeutronFlux	(	std::vector< double >	a_neutronEnergy,
		std::vector< double >	a_neutronEnergyError,
		std::vector< double >	a_efficiency,
		std::vector< double >	a_efficiencyError,
		std::vector< double >	a_measIntensity,
		std::vector< double >	a_measIntensityError,
		std::vector< std::vector< double >>	a_trueEnergyDistribution
	)

calculating average efficiency over measuredEn bin = sum (trueEn) * efficiency(trueEn)

◆ fitLightVNeutronEnergyHist()

std::vector< std::vector< double > > STOFFluxAnalysis::fitLightVNeutronEnergyHist	(	TH2 *	a_histogram,
		double	a_minEnergy,
		double	a_maxEnergy,
		double	a_minLight,
		double	a_maxLight,
		int	a_numberOfBinPerProj
	)

function to automatically fit TH2D containing some linear background and a Gaussian like feature corresponding to the light deposited in the target scintillator as a function of neutron energy returns vectors of: neutron energy (bin centroid) neutron energy binwidth/2 integral of gaussian feature uncertainty on integral !!!this doesn't currently treat bins where the feature is partially cut properly

find bin associated with min/max energy

getting info about energy of bins

getting projection

SpectrumAnalysis fitter needs TH1F
