Detailed Description

PndCATrackLinearisationVector class describes the parameters which are used to linearise the transport equations for the track trajectory.

The class is used during track (re)fit, when the PndCATrackParam track is only partially fitted, and there is some apriory knowledge about trajectory. This apriory knowledge is used to linearise the transport equations.

In case the track is fully fitted, the best linearisation point is the track trajectory itself (PndCATrackLinearisationVector = PndCATrackParamVector ).
