Detailed Description

Output action To add some output to actions, TGo4FitterOutput action class should be used.

In constructor output command and options (if required) should be specified. Also AddOuputAction() routine of fitter can be used. Now following commands are available: "Print". Possible options are: "*"- print all internal objects, "**" - print also objects in slots, "Pars" - print parameters values, "Ampls" - only amplitude parameters, "Results" - result values. "Draw". Draw of the fitter data and model objects. As option name of data object and its components should be sets up. For instance, "data1,Gauss1,Gauss2". If first character will be "#", Draw command creates new canvas for output.

Perform simple peak finder algorithm.

Seeks for gaussians with amplitude more than given threshold (AmplThreshold introduced relative to maximum data value, from 0 to 1), with width in range between MinWidth and MaxWidth. Polynomial approximation can be applied for background appoximation(PolOrder>=0) or not used (PolOrder<0). Only selected by range conditions data part will be used by peak finder. Appropriate number of gaussians will be placed in list of models and associate with data.
