Description

Kalman filter package (KF)

Kalman filter tools of the CBM experiment adapted for BM@N : track fit in the inhomogeneous magnetic field with the material effects, primary and secondary vertex finding, and the reconstruction of short-lived particles (KF Particle). In run_reco_bmn.C, CbmKF is initialized before the CA tracking (cat), the primary vertex is found by CbmPVFinderKF and BmnKFPrimaryVertexFinder.

Classes
