Memory of the SZ fitter fitting sz lines to the stereo segments.
CDCRiemannFitter m_riemannFitter
Memory of the Riemann fitter for the circle fits.
const CDCSZFitter & getSZFitter() const
Returns the sz fitter instance that is used by this filter.
const CDCRiemannFitter & getFitter2D() const
Returns the xy fitter instance that is used by this filter.
Abstract base class for different kinds of events.
