Detailed Description

A class describing a Gaussian resolution, parametrized for MET.

This class offers a simple parameterization of a resolution. The parameterization is a Gaussian with a width of a constant times the square root of the true parameter.

Constructor & Destructor Documentation

KLFitter::ResGauss_MET::ResGauss_MET ( std::vector< double > const &  parameters )

explicit

A constructor.

Parameters

parameters

The parameters of the parameterization.

Member Function Documentation

double KLFitter::ResGauss_MET::GetSigma ( double  sumet )

overridevirtual

Return the width of the TF depending on the value of sumET.

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

Parameters

sumet

SumET as parameter for the MET TF.

Returns

The width.

Implements KLFitter::ResolutionBase.

double KLFitter::ResGauss_MET::logp ( double  x, double  xmeas, bool *  good, double  sumet  )

overridevirtual

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.
sumet	SumET, as the width of the TF depends on this.

Returns

Logarithm of the probability.

Reimplemented from KLFitter::ResolutionBase.

void KLFitter::ResGauss_MET::SetSigma ( double  sigma )

inline

Set the width of the Gaussian.

Parameters

sigma

The width of the Gaussian.
