Detailed Description

ArgusBG PDF builder.

Build RooArgusBG Pdf.

Config Directives:

/// configStr = ArgusBG ["<Optional Title>"]
/// x = AbsReal Def
/// max = AbsReal Def
/// c = AbsReal Def
/// pow = AbsReal Def

x is the default observable. max is the end point of the pdf, usually a constant. c is the slope parameter of the pdf. pow is the power of the multiplying term (normally 1/2). All the variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarArgusBG::rarArgusBG

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 40 of file rarArgusBG.cc.

References init().

  : rarBasePdf(),
    _x(0), _max(0), _c(0), _pow(0)
{
  init();
}

rarArgusBG::rarArgusBG	(	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 rarArgusBG.cc.

References init().

  : rarBasePdf(configFile, configSec, configStr,
               theDatasets, theData, name, title),
    _x(0), _max(0), _c(0), _pow(0)
{
  init();
}

void rarArgusBG::init

(

)

[protected, virtual]

Initial function called by ctor.

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

Reimplemented from rarBasePdf.
