Detailed Description

The MeasurementEstimator defines the compatibility of a TrajectoryStateOnSurface and a RecHit, and of a TrajectoryStateOnSurface and a Plane. It is used in the Det interface to obtain compatible measurements.

Member Function Documentation

◆ clone()

virtual MeasurementEstimator* MeasurementEstimator::clone ( ) const

pure virtual

Implemented in OuterEstimator< Algo >, EtaPhiEstimator, ConversionBarrelEstimator, ConversionForwardEstimator, Chi2Switching1DEstimator, EtaPhiMeasurementEstimator, GsfChi2MeasurementEstimator, MRHChi2MeasurementEstimator, Chi2MeasurementEstimator, Chi2Strip1DEstimator, and InsideBoundsMeasurementEstimator.

◆ estimate() [1/2]

virtual SurfaceReturnType MeasurementEstimator::estimate	(	const TrajectoryStateOnSurface &	ts,
		const Plane &	plane
	)		const

pure virtual

Returns true if the TrajectoryStateOnSurface is compatible with the Plane, false otherwise. The TrajectoryStateOnSurface must be on the plane.

Implemented in EtaPhiMeasurementEstimator, ConversionBarrelEstimator, ConversionForwardEstimator, InsideBoundsMeasurementEstimator, and Chi2MeasurementEstimatorBase.

◆ estimate() [2/2]

virtual HitReturnType MeasurementEstimator::estimate	(	const TrajectoryStateOnSurface &	ts,
		const TrackingRecHit &	hit
	)		const

pure virtual

Returns pair( true, value) if the TrajectoryStateOnSurface is compatible with the RecHit, and pair( false, value) if it is not compatible. The TrajectoryStateOnSurface must be on the same Surface as the RecHit. For an estimator where there is no value computed, e.g. fixed window estimator, only the first(bool) part is of interest.

Implemented in EtaPhiEstimator, MRHChi2MeasurementEstimator, InsideBoundsMeasurementEstimator, MRHChi2MeasurementEstimator, OuterEstimator< Algo >, ConversionBarrelEstimator, ConversionForwardEstimator, Chi2MeasurementEstimatorBase, Chi2Switching1DEstimator, MuonChi2MeasurementEstimator, GsfChi2MeasurementEstimator, EtaPhiMeasurementEstimator, Chi2MeasurementEstimator, and Chi2Strip1DEstimator.

◆ maximalLocalDisplacement()

virtual Local2DVector MeasurementEstimator::maximalLocalDisplacement	(	const TrajectoryStateOnSurface &	ts,
		const Plane &	plane
	)		const

pure virtual

Returns the size of the compatibility region around the local position of the TrajectoryStateOnSurface along the directions of local x and y axis. The TrajectoryStateOnSurface must be on the plane. This method allows to limit the search for compatible detectors or RecHits. The MeasurementEstimator should not return "true" for any RecHit or Plane which is entirely outside of the compatibility region defined by maximalLocalDisplacement().

Implemented in EtaPhiMeasurementEstimator, ConversionBarrelEstimator, ConversionForwardEstimator, InsideBoundsMeasurementEstimator, and Chi2MeasurementEstimatorBase.
