Detailed Description

Class storing the result of the Maximum Likelihood fit of Multiple Coulomb Scattering angles between segments within a Track or Trajectory.

Class storing the result of the Maximum Likelihood fit of Multiple Coulomb Scattering angles between segments within a Track or Trajectory. It stores: the resulting momentum, momentum uncertainty, and best likelihood value (both for fwd and bwd fit); the vectors of segment (radiation) lengths and of scattering angles; the PID hypothesis used in the fit.
