18// AliTOFTrackV2 class
19//
20// Author: F. Pierella | pierella@bo.infn.it
21//
22// Description: output of AliTOFReconstructionerV2
23// TRD tracking capabilities have been foreseen by including the member
24// variables fxTRD, fyTRD, fzTRD and momentum components fPxTRD, fPyTRD, fPzTRD.
25// Class to be written in TreeR for each event.
26//
27// Member variable summary description:
28// - track momentum and position in the last TPC padrow
29// - track length as given by the geometrical propagation
30// - reconstructed mass from time of flight and time of flight itself
da3d3acd 31// - fMatchingStatus
32// -2 backpropagation goes out of the z acceptance of the TOF
33// -1 failed backpropagation on TOF inner radius
34// 0 for fake tracks
35// 1 for tracks matched with no signal on TOF (failed DigitFinder)
36// 3 for tracks matched with the actual digit
37// 4 for tracks matched with a wrong (not its own) TOF digit
