Constructor & Destructor Documentation

KLFitter::ResolutionBase::ResolutionBase ( int  npar )

explicit

The default constructor.

Parameters

npar	The number of parameters needed for the parameterization.

KLFitter::ResolutionBase::ResolutionBase ( std::vector< double >  parameters )

explicit

A constructor.

Parameters

parameters

A vector with the parameters.

Member Function Documentation

virtual double KLFitter::ResolutionBase::GetSigma ( double  par )

pure virtual

Return the (approximate) width of the TF depending on the relevant parameter (mostly xmeas, but sumET in case of ResGauss_MET).

Use to adjust the range of the fit parameter that correspond to the TF.

Parameters

par	Parameter on which the width depends

Returns

The width.

Implemented in KLFitter::ResDoubleGaussBase, KLFitter::ResSingleGaussLinearBase, KLFitter::ResGaussE, KLFitter::ResGaussPt, KLFitter::ResSingleGaussMET, KLFitter::ResCrystalBallJets, KLFitter::ResGauss_MET, KLFitter::ResGauss, KLFitter::ResSingleGaussBase, KLFitter::ResSingleGaussE, and KLFitter::ResSingleGaussPt.

virtual double KLFitter::ResolutionBase::logp ( double  , double  , bool *  good, double  = 0  )

inlinevirtual

Return the probability of the true value of x given the measured value, xmeas.

Parameters

x	The true value of x.
xmeas	The measured value of x.
good	False if problem with TF.
par	Optional additional parameter (SumET in case of MET TF).

Returns

Logarithm of the probability.

Reimplemented in KLFitter::ResDoubleGaussBase, KLFitter::ResSingleGaussLinearBase, KLFitter::ResGaussE, KLFitter::ResGaussPt, KLFitter::ResGauss_MET, KLFitter::ResCrystalBallBase, KLFitter::ResGauss, and KLFitter::ResSingleGaussBase.

int KLFitter::ResolutionBase::Par	(	int	index,
		double *	par
	)

Return a parameter of the parameterization.

Parameters

index	The parameter index.
par	The parameter value.

Returns

An error flag.

int KLFitter::ResolutionBase::ReadParameters	(	const char *	filename,
		std::size_t	nparameters
	)

Read parameter values from ASCII file.

Parameters

filename	The name of the file.
nparameters	The number of parameters.

Returns

An error code.

int KLFitter::ResolutionBase::SetPar	(	int	index,
		double	value
	)

Set a parameter value.

Parameters

index	The parameter index.
value	The parameter value.

Returns

An error code.

int KLFitter::ResolutionBase::SetPar

(

std::vector< double >

parameters

)

Set all parameter values.

Parameters

parameters

A vector of parameters.

Returns

An error code.

int KLFitter::ResolutionBase::Status ( )

inline

Return a status code.

Returns

A status code (1: ok, 0: error).
