Detailed Description

Root object representing a reconstructed particle track.

Represents a reconstructed particle track. It could be a charged particle track or a photon that is reconstructed due to it's conversion into an electron-positron pair.

A track contains two lists:

1.) A list of TkrLocator objects which contain the position and angle of the track at different interesting positions (e.g.: initial point, exit point of the tracker).

2.) A list of TkrHit objects which point to the TkrSiCluster objects that are associated with this track.
