Returns true if the TrajectoryStateOnSurface is compatible with the BoundPlane, false otherwise.

The TrajectoryStateOnSurface must be on the plane.

std::pair< bool, double > BarrelMeasurementEstimator::estimate	(	const TrajectoryStateOnSurface &	ts,
		const TransientTrackingRecHit &	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.

MeasurementEstimator::Local2DVector BarrelMeasurementEstimator::maximalLocalDisplacement	(	const TrajectoryStateOnSurface &	ts,
		const BoundPlane &	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 BoundPlane which is entirely outside of the compatibility region defined by maximalLocalDisplacement().
