Detailed Description

RooVoigtian PDF builder.

Build RooVoigtian Pdf.

Config Directives:

/// configStr = Voigtian ["<Optional Title>"]
/// x = AbsReal Def
/// mean = AbsReal Def
/// sigma = AbsReal Def

x is the default observable. mean is the mean of the Breit-Wigner PDF. width is the width of the Breit-Wigner PDF. sigma is the width of gaussian that is convoluted with the Breit-Wigner PDF. All the variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarVoigtian::rarVoigtian

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 40 of file rarVoigtian.cc.

References init().

  : rarBasePdf(),
    _x(0), _mean(0), _width(0), _sigma(0)
{
  init();
}

rarVoigtian::rarVoigtian	(	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 rarVoigtian.cc.

References init().

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

void rarVoigtian::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 RooVoigtian PDF with _pdfType being Voigtian, respectively.

Reimplemented from rarBasePdf.

Definition at line 80 of file rarVoigtian.cc.
