Detailed Description

Prints the content of all the tracks on screen.

This analyser prints the content of all the tracks into the LogInfo/LogVerbatim stream. The associated objects are printed only if they were produced with the same input tag as the tracks.

Configuration parameters

• TrackModuleLabel (string, required): label of the producer used to create the recob::Track collection to be dumped
• OutputCategory (string, default: "DumpTracks"): the category used for the output (useful for filtering)
• WayPoints (unsigned integer, default: 10): approximate number of way points printed in the output
• SpacePointAssociations (boolean, default: true): prints the number of space points associated with the tracks
• PrintSpacePoints (boolean, default: false): print the index of all hits associated with the tracks
• HitAssociations (boolean, default: true): prints the number of hits associated with the tracks
• PrintHits (boolean, default: false): print the index of all hits associated with the tracks
• ParticleAssociations (boolean, default: true): prints the number of particle-flow particles associated with the tracks
