Track Matching Definitions

Introduction

Given that each hit has been assigned (at least) one track label, we would like to quantify how well the labelling was performed. A key set of metrics are: - What proportion of particles were "reconstructed" by a track - What proportion of tracks were used to reconstruct particles, which we shall call being "matched" to a particle Exactly how we define the goodness of reconstruction and matching is somewhat arbitrary, but there exist some common definitions.

Styles of Matching
