Detailed Description

Exponential PDF builder.

Build RooBallack Pdf.

Config Directives:

/// configStr = Exp ["<Optional Title>"]
/// x = AbsReal Def
/// mean  = AbsReal Def
/// width = AbsReal Def
/// tail  = AbsReal Def
/// alpha = AbsReal Def
/// n     = AbsReal Def

x is the default observable. mean is the peak position of the pdf. width is the width of the pdf. tail is the tail parameter of the pdf. alpha is the atachment point of the polynomial tail. n is the power of the polynomial of the pdf. All the variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarBallack::rarBallack

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 43 of file rarBallack.cc.

References init().

  : rarBasePdf(),
    _x(0), _mean(0), _width(0), _tail(0), _alpha(0), _n(0)
{
  init();
}

rarBallack::rarBallack	(	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 62 of file rarBallack.cc.

References init().

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

void rarBallack::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 the RooBallack PDF.

Reimplemented from rarBasePdf.

Definition at line 82 of file rarBallack.cc.
