Class representing a pair of reconstructed axial segements in adjacent superlayer.
Class implementing the Riemann fit for two dimensional trajectory circle.
A reconstructed sequence of two dimensional hits in one super layer.
Definition: CDCSegment2D.h:39
Particle trajectory as it is seen in xy projection represented as a circle.
Base class for filters on a generic object type.
Definition: Filter.dcl.h:29
Filter for the constuction of axial to axial segment pairs based on simple criterions.
const CDCTrajectory2D & getFittedTrajectory2D(const CDCAxialSegment2D &segment) const
Returns the trajectory of the axial segment. Also fits it if necessary.
Weight operator()(const CDCAxialSegmentPair &axialSegmentPair) final
Checks if a pair of axial segments is a good combination.
const CDCRiemannFitter & getRiemannFitter() const
Returns the xy fitter instance that is used by this filter.
CDCRiemannFitter m_riemannFitter
Memory of the Riemann fitter for the circle fits.
Abstract base class for different kinds of events.
