Constructor & Destructor Documentation

EtaPhiEstimator::EtaPhiEstimator ( double  eta,
double  phi,
const Chi2MeasurementEstimatorBase estimator 
)
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 BoundPlane and maximalLocalDisplacement.

EtaPhiEstimator(double eta, double phi, const Chi2MeasurementEstimatorBase *estimator)
virtual std::pair<bool,double> EtaPhiEstimator::estimate ( const TrajectoryStateOnSurface ts,
const TransientTrackingRecHit hit 
) const
inlinevirtual

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.
