Detailed Description

RooGaussModel PDF builder.

Build RooGaussModel Pdf.

Config Directives:

/// configStr = GaussModel ["<Optional Title>"]
/// x = RealVar Def
/// mean = AbsReal Def
/// sigma = AbsReal Def
/// msSF = AbsReal Def
/// meanSF = AbsReal Def
/// sigmaSF = AbsReal Def
/// FlatScaleFactorIntegral = <yes|no>

x is the default observable (deltaT) and should be RooRealVar. mean is the mean of the PDF. sigma is the sigma of the PDF. msSF is the scale factor for both mean and sigma. meanSF is the mean scale factor of the PDF. sigmaSF is the sigma scale factor of the PDF. One can choose to specify msSF for both mean and sigma, or choose meanSF for mean, and/or sigmaSF for sigma, or if none is chosen, the default values are 1. All the AbsReal parameters can be RooRealVar or RooFormulaVar. If optional FlatScaleFactorIntegral is set to no (default yes), RooGaussModel::advertiseFlatScaleFactorIntegral will be called with kFALSE, otherwise with kTRUE.

Constructor & Destructor Documentation

rarGaussModel::rarGaussModel

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 40 of file rarGaussModel.cc.

References init().

  : rarBasePdf(),
    _x(0), _mean(0), _sigma(0), _msSF(0), _meanSF(0), _sigmaSF(0)
{
  init();
}

rarGaussModel::rarGaussModel	(	const char *	configFile,
		const char *	configSec,
		const char *	configStr,
		rarDatasets *	theDatasets,
		RooDataSet *	theData,
		const char *	name,
		const char *	title
	)

Default ctor.

Parameters:

	configFile	The config file
	configSec	The config section
	configStr	The config string
	theDatasets	Available datasets
	theData	Default dataset for this PDF
	name	The name
	title	The title

The default ctor first initializes data members, and then calls init.

Definition at line 59 of file rarGaussModel.cc.

References init().

  : rarBasePdf(configFile, configSec, configStr,
               theDatasets, theData, name, title),
    _x(0), _mean(0), _sigma(0), _msSF(0), _meanSF(0), _sigmaSF(0)
{
  init();
}

void rarGaussModel::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor. It first creates the parameters by calling createAbsReal, and finally it builds RooGaussModel PDF.

Reimplemented from rarBasePdf.
