Detailed Description

Produce a reco::Track collection, as a result of the fit of an existing recob::TrackTrajectory collection.

This producer takes an input an existing recob::TrackTrajectory collection (and the associated hits) and fits it. The mandatory output are: the resulting recob::Track collection, the associated hits, and the association between the input TrackTrajectory and the output Track. Optional outputs are recob::TrackFitHitInfo and recob::SpacePoint collections, plus the Assns of SpacePoints to Hits. An option is provided to create SpacePoints from the TrajectoryPoints in the Track. The fit is performed by an user-defined tool, which must inherit from larreco/TrackFinder/TrackMaker.

Parameters: trackMaker (fhicl::ParameterSet for the trkmkr::TrackMaker tool used to do the fit), inputCollection (art::InputTag of the input recob::TrackTrajectory collection), doTrackFitHitInfo (bool to decide whether to produce recob::TrackFitHitInfo's), doSpacePoints (bool to decide whether to produce recob::SpacePoint's), and spacePointsFromTrajP (bool to decide whether the produced recob::SpacePoint's are taken from the recob::tracking::TrajectoryPoint_t's of the fitted recob::Track).
