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().

00042     _x(0), _max(0), _c(0), _pow(0)

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

Default ctor.

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.

Member Function Documentation

rarArgusBG::ClassDef ( rarArgusBG  ,
) [private]

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.

Definition at line 79 of file rarArgusBG.cc.
