std::pair< bool, double > ConversionForwardEstimator::estimate ( const TrajectoryStateOnSurface ts,
const TrackingRecHit hit 
) 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 MeasurementEstimator.

virtual bool ConversionForwardEstimator::estimate ( const TrajectoryStateOnSurface ts,

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

Implements MeasurementEstimator.

MeasurementEstimator::Local2DVector ConversionForwardEstimator::maximalLocalDisplacement ( const TrajectoryStateOnSurface ts,
const Plane plane 
) const
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().
