Detailed Description

This class describes the reconstructed tracks that are stored in the AOD and RECO. It also contains a reference to more detailed information about each track, that is stoed in the TrackExtra object, available only in RECO.

Note that most of the functions provided in this Track class rely on the existance of the TrackExtra object, so will not work on AOD.

The most useful functions are those provided in the TrackBase class from which this inherits, all of which work on AOD.
