Abstract base class for all kind of linearizedtrack like objects. Calculates and stores the ImpactPointMeasurement of the impact point (point of closest approach in 3D) to the given linearization point. (see V.Karimaki, HIP-1997-77 / EXP)
Computes the parameters of the trajectory at the transverse point of closest approach (in the global transverse plane) to the linearization point, and the jacobiam matrices. (see R.Fruehwirth et al. Data Analysis Techniques in HEP Experiments Second Edition, Cambridge University Press 2000, or R.Fruehwirth et al. Vertex reconstruction and track bundling at the LEP collider using robust algorithms. Computer Physics Communications 96 (1996) 189-208).
