Detailed Description

A graphical interface for placing schematic peak onto a 1D histogram with a given position, height and FWHM.

Background limits left and right respect to the peak centroid could be placed.

A function (TF1) is associated to the peak, gaussian and landau are pre-defined but the user could defined a customized function based on a TFormula expression (don't use C defined function)

The user could choose between a linear or a quadratic fit in the given windows for the background.

A example for gaussian fit with linear background for gamma ray spectrum (radware spectrum):

// open spectrum with HistoDB class (see this class for details)
 Gw::HistoDB db;
 db.Open("toto", "rad:$PWD");
 TH1F* h = new TH1F();
 h->SetName("Eu152.spe");
 db >> *h;
 h->SetAxisRange(600, 800);
 h->Draw();
// set peak
 Gw::Peak1D* p = new Gw::Peak1D("PeakName", "PeakTitle"); 
 p->SetPeak(689, 79631, 4.0); // position height and FWHM, first guess
 p->SetBackground(640, 650, 712, 728); // set background left and right for lower and upper limits
 p->Draw(""); // option "f" fill the peak with the given attribute
// fit the spectrum with the given function and initialize with the parameters of the peak
 p->SetFunction("gaus");
 p->Fit("lin"); // fit histogram with gaus and linear background functions in the current pad (histogram has to exist)
 p->Draw(); // draw peak with new parameters from fit.
