Introduction

This package contains algorithms to validate the common tracking. This includes an algorithm to fill validation ntuples with track data. The algorithm is based on the tools in the TrkValTools package, see the documentation of this package for more information about the ntuple variables, etc.

Class Overview

The TrkValAlgs package contains the following classes:

• Trk::TrackValidationNtupleWriter : Alg for filling a validation ntuple with Trk::Track information using Trk::IValidationNtupleTool. It retrieves a track collection from StoreGate and loops over all contained tracks.
• Trk::SingleTrackDiffAlg : Alg for a simple track diff. The Trk::ITrackDiff tool is used to perform the comparison. This alg can be used for single track events, because only the first track of the reference collection will be compared with the best matching track of the comparison collection.

How to use the algorithms

The Trk::TrackValidationNtupleWriter needs a configured instance of the Trk::BasicValidationNtupleTool. This tool can be configured by the Python setup class ConfiguredBasicValidationNtupleTool which is included in the TrkValTools package. An example can be found in the TrkTrackValidationNtupleWriter.py jobOption fragment.
