ConformalTrackingV2

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

[VXDBarrel]

@Parameters : MaxCellAngle : 0.005; MaxCellAngleRZ : 0.005; Chi2Cut : 100; MinClustersOnTrack : 4; MaxDistance : 0.02; SlopeZRange: 10.0; HighPTCut: 10.0;
@Flags : HighPTFit, VertexToTracker, KalmanFitForward
@Functions : CombineCollections, BuildNewTracks
[VXDEncap]
@Collections : VXDEndcapTrackerHits
@Parameters : MaxCellAngle : 0.005; MaxCellAngleRZ : 0.005; Chi2Cut : 100; MinClustersOnTrack : 4; MaxDistance : 0.02; SlopeZRange: 10.0; HighPTCut: 10.0;
@Flags : HighPTFit, VertexToTracker, KalmanFitForward

[LowerCellAngle1]
@Collections : VXDTrackerHits, VXDEndcapTrackerHits
@Parameters : MaxCellAngle : 0.025; MaxCellAngleRZ : 0.025; Chi2Cut : 100; MinClustersOnTrack : 4; MaxDistance : 0.02; SlopeZRange: 10.0; HighPTCut: 10.0;
@Flags : HighPTFit, VertexToTracker, RadialSearch, KalmanFitForward
@Functions : CombineCollections, BuildNewTracks
[LowerCellAngle2]
@Collections :
@Parameters : MaxCellAngle : 0.05; MaxCellAngleRZ : 0.05; Chi2Cut : 2000; MinClustersOnTrack : 4; MaxDistance : 0.02; SlopeZRange: 10.0; HighPTCut: 10.0;
@Flags : HighPTFit, VertexToTracker, RadialSearch, KalmanFitForward
@Functions : BuildNewTracks, SortTracks
[Tracker]
@Collections : ITrackerHits, OTrackerHits, ITrackerEndcapHits, OTrackerEndcapHits
@Parameters : MaxCellAngle : 0.05; MaxCellAngleRZ : 0.05; Chi2Cut : 2000; MinClustersOnTrack : 4; MaxDistance : 0.02; SlopeZRange: 10.0; HighPTCut: 1.0;
@Flags : HighPTFit, VertexToTracker, RadialSearch, KalmanFitForward
@Functions : CombineCollections, ExtendTracks
[Displaced]
@Collections : VXDTrackerHits, VXDEndcapTrackerHits, ITrackerHits, OTrackerHits, ITrackerEndcapHits, OTrackerEndcapHits
@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 or colon, 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
