Detailed Description

Track from a non-cascading particle.

A recob::Track consists of a recob::TrackTrajectory, plus additional members relevant for a "fitted" track:

• fit χ²
• number of degrees of freedom
• particle ID hypothesis used in the fit (if any)
• covariance matrices at start (vertex) and end positions.

Please refer to the recob::TrackTrajectory documentation for more information about it.

In terms of interface, recob::Track extends recob::TrackTrajectory, so that methods of the stored recob::TrackTrajectory can be called directly from the recob::Track interface, e.g.:

size_t       NumberTrajectoryPoints()         const { return fTraj.NumberTrajectoryPoints(); }

Two different parameter conventions are used in a recob::Track, and functions to convert from one to the other are provided:

1. Trajectory points and momenta (or directions) are in form of 3-vectors, corresponding to a global Cartesian 6D representation
2. Covariance matrices are stored in a Local 5D representation (so that the covariance matrix is invertible), where the parameters are defined on the plane orthogonal to the track direction at a given track point. By construction the local parameters of the track itself are (0,0,0,0,1/p). See lardataobj/RecoBase/TrackingPlane.h for more information.
