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
Class representing a pair of one reconstructed axial segement and one stereo segment in adjacent supe...
Particle trajectory as it is seen in xy projection represented as a circle.
Particle full three dimensional trajectory.
Filter for the constuction of axial to axial segment pairs based on simple criterions.
const CDCRiemannFitter & getRiemannFitter() const
Returns the xy fitter instance that is used by this filter.
const CDCTrajectory2D & getFittedTrajectory2D(const CDCSegment2D &segment) const
Returns the trajectory of the segment. Also fits it if necessary.
Weight operator()(const CDCSegmentPair &segmentPair) final
Checks if a pair of segments is a good combination.
CDCRiemannFitter m_riemannFitter
Memory of the Riemann fitter for the circle fits.
const CDCTrajectory3D & getFittedTrajectory3D(const CDCSegmentPair &segmentPair) const
Returns the three dimensional trajectory of the axial stereo segment pair.
Abstract base class for different kinds of events.
