Detailed Description

Threshold PDF builder.

Build RooThreshold Pdf.

Config Directives:

/// configStr = Threshold ["<Optional Title>"]
/// x = AbsReal Def
/// m0  = AbsReal Def
/// power = AbsReal Def
/// nOrder = <orderval>
/// P01 = AbsReal Def
/// P02 = ...
/// 

x is the default observable. m0 is the threshold. PDF= for x<m0. power is the power nOrder is an integer representing the order of the polynomial. P01 ... P<orderVal> define all the coeffs. P00 is not needed. All the floating variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarThreshold::rarThreshold

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 41 of file rarThreshold.cc.

References init().

  : rarBasePdf(),
    _x(0), _m0(0), _power(0), _nOrder(1)
{
  init();
}

rarThreshold::rarThreshold	(	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 60 of file rarThreshold.cc.

References init().

  : rarBasePdf(configFile, configSec, configStr,
               theDatasets, theData, name, title),
    _x(0), _m0(0), _power(0), _nOrder(1)
{
  init();
}

void rarThreshold::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 RooThreshold PDF.

Reimplemented from rarBasePdf.

Definition at line 82 of file rarThreshold.cc.
