The ConformalTrackingV2 processor is fully configurable via the steering file. The parameter Steps takes a "Config" like String. For example:

• SlopeZRange @Parameters : MaxCellAngle : 0.05; MaxCellAngleRZ : 0.05; Chi2Cut : 1000; MinClustersOnTrack : 5; MaxDistance : 0.015; SlopeZRange: 10.0; HighPTCut: 10.0; @Flags : OnlyZSchi2cut, RadialSearch, KalmanFitBackward @Functions : CombineCollections, BuildNewTracks

Each steps starts with a [Name] in brackets. Following are the @Collections, @Parameters, @Flags, and @Functions entries. All @ have to be present. The @Collections and @Flags can be empty. It does not make sense to leave the @Functions empty. The @Parameters needs to be present and all parameters need to be set. Parameters and values need to be separated by an equal sign, separation between parameters can be a comma, semicolon, or colon.

The @Parameters are

• MaxCellAngle
• MaxCellAngleRZ
• Chi2Cut
• MinClustersOnTrack
• MaxDistance
• SlopeZRange
• HighPTCut

Possible @Flags are

• OnlyZSchi2cut
• VertexToTracker
• RadialSearch
• HighPTFit
• KalmanFitForward
• KalmanFitBackward

Possible @Functions are

• CombineCollections
• BuildNewTracks
• ExtendTracks
• SortTracks
