self

)

Returns best-matching track, even for non-reconstructed TrackingParticles, or None, if there is no best-matching track.

Best-matching is defined as the one with largest number of
hits matched to the hits of a TrackingParticle (>= 3). If
there are many fulfilling the same number of hits, the one
inducing the innermost hit of the TrackingParticle is chosen.
