Detailed Description

Provides the abstract interface for track fitting in the common ATLAS Tracking EDM. This interfaces carries different methods for the main use cases of fitting, extending and re-fitting a track. The interface is held general so that it is suitable for global and progressive fitter algorithms. Each implementation can decide how they bundle these use cases onto a common maths core.

Member Function Documentation

fit() [1/6]

virtual std::unique_ptr<Track> Trk::ITrackFitter::fit ( const EventContext &  ctx, const MeasurementSet &  measSet, const TrackParameters &  params, const RunOutlierRemoval  runOutlier = false, const ParticleHypothesis  matEffects = Trk::nonInteracting  ) const

pure virtual

FIT A TRACK TO A SET OF MEASUREMENTBASE.

Main fit method. The TrackParameters is a first estimate for the track, represented close to the origin.

Implemented in Trk::iPatFitter, Trk::DistributedKalmanFilter, and Trk::GaussianSumFitter.

fit() [2/6]

virtual std::unique_ptr<Track> Trk::ITrackFitter::fit ( const EventContext &  ctx, const PrepRawDataSet &  prepRawSet, const TrackParameters &  params, const RunOutlierRemoval  runOutlier = false, const ParticleHypothesis  matEffects = Trk::nonInteracting  ) const

pure virtual

FIT A TRACK TO A SET OF PrepRawData.

Main fit method. The TrackParameters is a first estimate for the track, represented close to the origin. Use-cases can be thought of that make it necessary to control toggling outlier removal and material effects not via job options (once-per-job) but at each call (toggle within event, large set of fast fit followed by one final full fit).

Implemented in Trk::iPatFitter, Trk::DistributedKalmanFilter, and Trk::GaussianSumFitter.

fit() [3/6]

virtual std::unique_ptr<Track> Trk::ITrackFitter::fit ( const EventContext &  ctx, const Track &  track, const MeasurementSet &  measSet, const RunOutlierRemoval  runOutlier = false, const ParticleHypothesis  matEffects = Trk::nonInteracting  ) const

pure virtual

RE-FIT A TRACK, ADDING A FITTABLE MEASUREMENT SET.

this method will use the vector of measurements from the existing track and refit adding the new measurements. The code is in this class, but can be overwritten by inheriting classes.

Implemented in Trk::GaussianSumFitter, Trk::iPatFitter, and Trk::DistributedKalmanFilter.

fit() [4/6]

virtual std::unique_ptr<Track> Trk::ITrackFitter::fit ( const EventContext &  ctx, const Track &  track, const PrepRawDataSet &  prepRawSet, const RunOutlierRemoval  runOutlier = false, const ParticleHypothesis  matEffects = Trk::nonInteracting  ) const

pure virtual

RE-FIT A TRACK, ADDING A PRD SET.

this method will disintegrate the track back to PRD and call the fit(PRDset) method.

Implemented in Trk::GaussianSumFitter, Trk::iPatFitter, and Trk::DistributedKalmanFilter.

fit() [5/6]

virtual std::unique_ptr<Track> Trk::ITrackFitter::fit ( const EventContext &  ctx, const Track &  track, const RunOutlierRemoval  runOutlier = false, const ParticleHypothesis  matEffects = Trk::nonInteracting  ) const

pure virtual

RE-FIT A TRACK.

Implemented in Trk::GaussianSumFitter, Trk::iPatFitter, and Trk::DistributedKalmanFilter.

fit() [6/6]

virtual std::unique_ptr<Track> Trk::ITrackFitter::fit ( const EventContext &  ctx, const Track &  track1, const Track &  track2, const RunOutlierRemoval  runOutlier = false, const ParticleHypothesis  matEffects = Trk::nonInteracting  ) const

pure virtual

COMBINE TWO TRACKS BY REFITTING.

Specifically designed for combined muon fits, allowing to extract extra informations (ID-exit & MS-entrance parameters, layers, Mefos) from already fitted tracks.

Implemented in Trk::GaussianSumFitter, Trk::iPatFitter, and Trk::DistributedKalmanFilter.
