Function Documentation

◆ doInterpolationPeakFindingAbby()

void UCorrelator::peakfinder::doInterpolationPeakFindingAbby	(	const TH2D *	hist,
		FineMaximum *	peak
	)

Legacy interpolation peak finding as Abby did it... basically does interpolation independently in row and column

Definition at line 401 of file PeakFinder.cc.

◆ doInterpolationPeakFindingBicubic()

void UCorrelator::peakfinder::doInterpolationPeakFindingBicubic	(	const TH2D *	hist,
		FineMaximum *	peak,
		double	min_to_consider = `0.75`
	)

NOT IMPLEMENTED YET. Eventually, this will find the maximum of the bicubic interpolant in the maximum bin

Definition at line 813 of file PeakFinder.cc.

◆ doPeakFindingGaussian()

void UCorrelator::peakfinder::doPeakFindingGaussian	(	const TH2D *	hist,
		FineMaximum *	peak
	)

2D gaussian fit to histogram.... this will be pretty slow

Definition at line 632 of file PeakFinder.cc.

◆ doPeakFindingHistogram()

void UCorrelator::peakfinder::doPeakFindingHistogram	(	const TH2D *	hist,
		FineMaximum *	peak
	)

Fool-proof but stupid method of using histogram

Definition at line 875 of file PeakFinder.cc.

◆ doPeakFindingQuadratic9()

void UCorrelator::peakfinder::doPeakFindingQuadratic9	(	const TH2D *	hist,
		FineMaximum *	peak
	)

These all do a quadratic fit in the neighbhorhood of the maximum bin. The number denotes the size of the square. This should be very fast; the matrix decomposition necessary to perform the minimization is statically computed.

Definition at line 374 of file PeakFinder.cc.

◆ findIsolatedMaxima()

int UCorrelator::peakfinder::findIsolatedMaxima	(	const TH2D *	hist,
		double	distance,
		int	Nmaxima,
		RoughMaximum *	maxima,
		double	minPhi = `0.`,
		double	maxPhi = `0.`,
		double	minTheta = `0.`,
		double	maxTheta = `0.`,
		bool	exclude = `false`,
		bool	use_bin_center = `true`
	)

Finds largest Nmaxima isolated local maxima in a histogram. A maximum is local if it's bigger than any neighboring bins Returns the number found (which might be less than Nmaxima if there are insufficient isolated local maxima)
