Constructor & Destructor Documentation

MRHChi2MeasurementEstimator::MRHChi2MeasurementEstimator	(	double	maxChi2,
		double	nSigma = `3.`
	)

inlineexplicit

Construct with cuts on chi2 and nSigma. The cut on Chi2 is used to define the acceptance of RecHits. The errors of the trajectory state are multiplied by nSigma to define acceptance of Plane and maximalLocalDisplacement.

	)		const

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.

Implements Chi2MeasurementEstimatorBase.
