TrkRefitAlg Package

Introduction

This package provides a configurable Algorithm, Trk::ReFitTrack, to refit tracks. In can be used to refit tracks with a different fitter and/or track model, to re-create track parameters at each measurement previously lost through data conversion or compression, and to merge tracks from two single-track collections. The output is written to a new track collection.

Note that this package is not meant to provide a full reconstruction strategy. For example combined track fits or improved fit strategies after particle identification should be implemented inside the offline Reconstruction CVS realm.

Steering the Trk::ReFitTrack

Trk::ReFitTrack is set up using standard Gaudi/Athena configurables

from TrkRefitAlg.TrkRefitAlgConf import Trk__ReFitTrack MyReFitTrack = Trk__ReFitTrack (name = "MyRefitTrack", FitterTool = ... ) topSequence += MyReFitTrack
