Detailed Description

Class TwoBodyDecayEstimator estimates the decay parameters and the corresponding error matrix (see TwoBodyDecayParameter) from two linearized tracks, and an hypothesis for the primary particle's mass and width as well as the mass of the secondary particles. It utilizes a robust M-estimator.
