Detailed Description

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

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

Inputs are: a Track or Trajectory, and various fit parameters (pIdHypothesis, minNumSegments, segmentLength, pMin, pMax, pStep, angResol)

Outputs are: a recob::MCSFitResult, containing: resulting momentum, momentum uncertainty, and best likelihood value (both for fwd and bwd fit); vector of comulative segment (radiation) lengths, vector of scattering angles, and PID hypothesis used in the fit. Note that the comulative segment length is what is used to compute the energy loss, but the segment length is actually slightly different, so the output can be used to reproduce the original results but they will not be identical (but very close).
