Constructor & Destructor Documentation

TSpectrum2Fit::TSpectrum2Fit ( void )

TSpectrum2Fit::TSpectrum2Fit ( Int_t numberPeaks )

numberPeaks: number of fitted peaks (must be greater than zero) the constructor allocates arrays for all fitted parameters (peak positions, amplitudes etc) and sets the member variables to their default values.

One can change these variables by member functions (setters) of TSpectrumFit class. Begin_Html

SETTER FUNCTION.

This function sets the following fitting parameters of peaks: -sigmaX - initial value of sigma x parameter -fixSigmaX - logical value of sigma x parameter, which allows to fix the parameter (not to fit) -sigmaY - initial value of sigma y parameter -fixSigmaY - logical value of sigma y parameter, which allows to fix the parameter (not to fit) -ro - initial value of ro parameter (correlation coefficient) -fixRo - logical value of ro parameter, which allows to fix the parameter (not to fit) -positionInitX - aray of initial values of peaks x positions -fixPositionX - array of logical values which allow to fix appropriate x positions (not fit). However they are present in the estimated functional. -positionInitY - aray of initial values of peaks y positions -fixPositionY - array of logical values which allow to fix appropriate y positions (not fit). However they are present in the estimated functional. -ampInit - aray of initial values of 2D peaks amplitudes -fixAmp - aray of logical values which allow to fix appropriate amplitudes of 2D peaks (not fit). However they are present in the estimated functional -ampInitX1 - aray of initial values of amplitudes of 1D ridges in x direction -fixAmpX1 - aray of logical values which allow to fix appropriate amplitudes of 1D ridges in x direction (not fit). However they are present in the estimated functional -ampInitY1 - aray of initial values of amplitudes of 1D ridges in y direction -fixAmpY1 - aray of logical values which allow to fix appropriate amplitudes of 1D ridges in y direction (not fit). However they are present in the estimated functional
