Detailed Description

Base class for 1D fit classes.

Note

Variables and functions used by fitting functions are static, which causes that some of them are defined twice, since they are already defined in the fit data class. The fit classes take care of this problem, so that static and non static variable remain consistant. These variables have to be static so that external fit functions can access them (like options, ...).

n	nombre d'entrées de l'histogramme

void RFitBase1D::Preset ( )

inlinevirtual

Parameters preset function before fit: in the base class, nothing is done (it may be overloaded in derived classes).

Reimplemented in RFitDecay.

Referenced by RGFitBase1D::GuiPreset().

Double_t RFitBase1D::Fit ( const char *  opts = "" )

virtual

Fonction qui réalise le fit de l'histogramme, et retourne le chi2 normalisé obtenu. En cas de normalisation des erreurs par le chi2, la valeur retournée est la valeur du chi2 avant la normalisation (ben, oui, après, il vaut 1, ça n'a pas tellement d'intérêt...).

Parameters

opts	options de fit (elles sont prioritaires sur les options internes, en particulier le mode de fit)

Reimplemented in RFitDecay.
