Go4Fit
Class TGo4FitModelGauss2

class TGo4FitModelGauss2

derived from TGo4FitModel

Two dimensional gaussian peak.

Has following parameters:
"Ampl" - amplitude;
"Pos0" - line position on first coordinate;
"Pos1" - line position on second coordinate;
"Width0" - line width on first coordinate;
"Width1" - line width on second coordinate;
"Cov0_1" - covariation between first and second coordinate.
By default, first coordinate associated with x axis, second - with y axis. To create instance of this model:

TGo4FitModelGauss2 *g = new TGo4FitModelGauss2("Gauss", 5., 5., 1., 1., 0.5);

where first parameter - name of model component, then initial value for positions, widths and covariation parameters are defined. To assigned coordinates to another axis, two more parameters should be used in the constructor:

TGo4FitModelGauss2 *g = new TGo4FitModelGauss2("Gauss", 5., 5., 1., 1., 0.5, 1, 2);

where 1 - assignment of first coordinate to y axis , 2 - assignment of second coordinate to z axis.
