KVGaussFitMassModifier Class Reference

Detailed Description

Change isotope masses in a multi-gauss fit by fixed offset.

This class will take an existing multi-gaussian fit KVMultiGaussIsotopeFit to the isotope distribution for a given element \(Z\) and shift the mass of each isotope by a constant \(\Delta A\), then refit the distribution according to a supplied experimental PID distribution

Example:

KVIDZAFromZGrid* gr; // pointer to grid to modify
 
KVGaussFitMassModifier gfmm(gr, 10); // prepare modification of masses for Z=10
 
TH2* hdata; // 2d identification map used with grid
auto pid_dist = gr->LinearizeHistoToPID(hdata); // generate 1d PID distribution to fit
 
gfmm.Modify(-1, pid_dist, KVItvFinderDialog::mass_fit_parameters); // decrease mass of all Z=10 isotopes by 1, refit the PID distribution

Note

For reasons beyond our ken, the default parameters for fitting the gaussians to PID spectra are part of the GUI class KVItvFinderDialog. They should obviously be part of KVMultiGaussIsotopeFit but this causes problems with ROOT/Cling which are for the moment incomprehensible.

KVGaussFitMassModifier()

KVGaussFitMassModifier::KVGaussFitMassModifier	(	KVIDZAFromZGrid *	gr,
		int	Z
	)

Prepare mass modification object for the multi-gaussian fit for element \(Z\) in the given grid.

Member Function Documentation

Modify()

void KVGaussFitMassModifier::Modify	(	int	deltaA,
		TH1 *	pid_dist,
		const KVNameValueList &	mass_fit_parameters
	)

Parameters

[in]	deltaA	mass modification \(\Delta A\) to apply to all isotopes of element, can be positive or negative
[in]	pid_dist	a PID distribution corresponding to the grid being used
[in]	mass_fit_parameters	parameters to control fit; by default KVMultiGaussIsotopeFit::mass_fit_parameters

Note

For any KVIDZAGrid, a 1-dimensional PID distribution to be used with multi-gaussian fits can be generated from a 2D identification map (e.g. \(\Delta E-E\) matrix) using KVIDZAFromZGrid::LinearizeHistoToPID()
