Detailed Description

A class to store vectors of input tracks in the cartesian parametrisation.

Author: M.Zyzak, I.Kisel

Date: 05.02.2019

Version: 1.0

A track is described with the state vector { X, Y, Z, Px, Py, Pz } and the corresponding covariance matrix. Also contains charge of the track, unique Id, assigned PDG hypothesis, charge, index of the corresponding primary vertex in case of primary track, number of hits from precise detectors (like MVD in CBM, HFT in STAR, ITS in ALICE, etc.) and the magnetic field approximation along the track trajectory (in case of nonhomogeneous CBM-like field).
The data model implemented in the class is "Structure Of Arrays": each parameter is stroed in a separate vector. Such data structure allows fast vectorised access to the aligned data providing the maximum possible speed for data reading, and at the same time easy random access to the data members. Tracks are sorted by KFParticleTopoReconstructor::SortTracks(): electrons, muons, pions, tracks without PID, kaons, protons, deuterons, tritons, He3, He4.
