Detailed Description

One dimensional gaussian peak.

Has following parameters :

• "Ampl" - amplitude,
• "Pos" - position of gaussian peak,
• "Width" - width of gaussian. In constructor initial values of these parameter and number of selected axis (0 - x axis, 1 - y axis and so on) should be setup:

TGo4FitModelGauss1 *g = new TGo4FitModelGauss1("Gauss", 10., 5., 1);

where "Gauss" - name of model component, "10." - peak position, "5." - peak width, "1" - selected axis (here - y).
