Constructor Detail

GaussFitter

public GaussFitter()

Constructor of a default wire scanner data fitter

Method Detail

setVariablesOn

public void setVariablesOn(boolean[] fit_on_arr)

Stes the variables that will be used in fitting. The input parameter is an 4-elements boolean array with true or false for the base line, center position, sigma, and amplitude of the Gaussian approximation.

guessAndFit

public boolean guessAndFit(WireScanData wsD)

Guess initial Gauss parameters and fit for both planes: X and Y

fitAgain

public boolean fitAgain(WireScanData wsD)

Fit for both planes X and Y without initial guess

guessAndFitX

public boolean guessAndFitX(WireScanData wsD)

Guess initial Gauss parameters and fit for X plane

guessAndFitY

public boolean guessAndFitY(WireScanData wsD)

Guess initial Gauss parameters and fit for Y plane

fitAgainX

public boolean fitAgainX(WireScanData wsD)

Fit for X plane without initial guess

fitAgainY

public boolean fitAgainY(WireScanData wsD)

Fit for Y plane without initial guess

setIterations

public void setIterations(int nIterations)

Sets the number of iterations diring the fitting

setGraphPoints

public void setGraphPoints(int nGraphPoints)

Sets the number of graph points in the fitting curve

setWidthCoeff

public void setWidthCoeff(double wCoeff)

Sets the width coefficient for fitting. The fit will use - wCoeff*sigma : + wCoeff*sigma region around pick for fitting

getIterations

public void getIterations(int nIterations)

Returns the number of iterations diring the fitting

getGraphPoints

public void getGraphPoints(int nGraphPoints)

Returns the number of graph points in the fitting curve

getWidthCoeff

public double getWidthCoeff()

Returns the width coefficient for fitting. The fit will use - wCoeff*sigma : + wCoeff*sigma region around pick for fitting
