Member Function Documentation

◆ calcPt()

double calcPt ( double const radius ) const

inlineprotected

Returns a value for the transverse momentum in GeV calculated from a provided radius.

Utilizing m_magneticFieldZ and hard coded speed of light

80{ return m_magneticFieldZ * radius * 0.00299792458; }

Belle2::QualityEstimatorBase::m_magneticFieldZ

double m_magneticFieldZ

Member storing the z component of the magnetic field.

Definition: QualityEstimatorBase.h:84

◆ estimateQuality()

virtual double estimateQuality ( std::vector< SpacePoint const * > const & measurements )

pure virtual

Minimal implementation of the quality estimation Calculates quality indicator in range [0,1].

measurements - std::vector<SpacePoint const*> ordered from innermost to outermost measurement

Implemented in QualityEstimatorRandom, QualityEstimatorCircleFit, QualityEstimatorLineFit3D, QualityEstimatorMC, QualityEstimatorRiemannHelixFit, and QualityEstimatorTripletFit.

◆ estimateQualityAndProperties()

virtual QualityEstimationResults estimateQualityAndProperties ( std::vector< SpacePoint const * > const & measurements )

inlinevirtual

Quality estimation providing additional quantities Calculates quality indicator in range [0,1] Optionally returns chi2 and additional informations.

Eg. momentum estimation.

measurements - std::vector<SpacePoint const*> ordered from innermost to outermost measurement

Reimplemented in QualityEstimatorTripletFit, and QualityEstimatorMC.

Definition at line 68 of file QualityEstimatorBase.h.

    {
      m_results = QualityEstimationResults();
      m_results.qualityIndicator = estimateQuality(measurements);
      return m_results;
    }

◆ setMagneticFieldStrength()

void setMagneticFieldStrength ( double magneticFieldZ = 1.5 )

inline

Setter for z component of magnetic field.

Parameters

magneticFieldZ : value to set it to

Member Data Documentation

◆ m_magneticFieldZ

double m_magneticFieldZ = 1.5

protected

Member storing the z component of the magnetic field.

Definition at line 84 of file QualityEstimatorBase.h.

◆ m_results

QualityEstimationResults m_results

protected

Result of the quality estimation This is stored as a member variable, because some values may be calculated by 'estimateQuality' anyways.

Therefore they don't need to be calculated explicitly in 'estimateQualityAndProperties'.
