Detailed Description

Reconstructs tracks from simulated particles.

See Also: TotallyCheatTracks example overview

This totally cheating tracking algorithm will return one lar::example::CheatTrack object for each simb::MCParticle inserted. The information of the track will perfectly reflect the content of the simulated particle trajectory.

Note: The produced track is not a standard LArSoft recob::Track.

Example of usage: ----------------------------------------------------------------—{.cpp} lar::example::TotallyCheatTrackingAlg cheaterAlg({}); cheaterAlg.setup();

std::vector<lar::example::CheatTrack> tracks; for (auto const& mcParticle: mcParticles)

tracks.push_back(cheaterAlg.makeTrack(mcParticle));

(assuming mcParticles a collection of simb::MCParticle).

Configuration

Currently, none.

Dependencies and setup

Currently none.

Member Function Documentation

lar::example::CheatTrack lar::example::TotallyCheatTrackingAlg::makeTrack ( simb::MCParticle const & mcParticle ) const

Returns a reconstructed track from the specified particle.

Parameters

mcParticle the simulated particle to be reconstructed

Returns: a reconstructed lar::example::CheatTrack track

The reconstucted track has one trajectory point per trajectory point of the input particle.
