El procesador produce TrackerHit a partir de SimTrackerHit del detector de vértices, del SET (External Si Tracker??) y del SIT (Intermediate Si Tracker). De acuerdo con la resolución especificada del punto, realiza un smearing gaussiano en la proyección del plano r − φ y z.

Each created TrackerHit is assigned the type via method TrackerHitImpl::setType(int type). The TrackerHit^? type is encoded in the following way : type = 100 + layer_index_vtx for vertex hits (layer_index_vtx = 1...5) type = 400 + layer_index_sit for SIT hits (layer_index_sit = 1,2) To access this type use method TrackerHit::getType()

• Input : collections of SimTrackerHits in vertex detector and SIT
• Output: collection of digitized TrackerHits in the vertex detector and SIT
• Parameters:
  • VTXCollectionName: The name of input collection of VTX SimTrackerHits (default name vxd00_VXD)
  • SITCollectionName: The name of input collection of SIT SimTrackerHits (default name sit00_SIT)
  • VTXHitCollection: The name of output collection of digitized VTX TrackerHits (default name VTXTrackerHits)
  • SITHitCollection: The name of output collection of digitized SIT TrackerHits (default name SITTrackerHits)
  • PointResolutionRPhi_VTX: Point resolution in r-phi for the vertex detector (in mm) (default value 0.004)
  • PointResolutionZ_VTX: Point resolution in z for the vertex detector (in mm) (default value 0.004)
  • PointResolutionRPhi_SIT: Point resolution in r-phi for SIT (in mm) (default value 0.01)
  • PointResolutionZ_SIT: Point resolution in z for SIT (in mm) (default value 0.01)
  • RemoveDrays: When this flag is set to 1 hits produced by delta-electrons are removed from output collections (default value 0)
  • MomentumCutForDRays: The upper cut on delta-electron momentum (in MeV) (default value 10)
  • Debug: When this flag is set to one, debugging regime is enabled with a lot of printouts (default value is 0)
• Input: SETCollection _SITCollection_ VXDCollection
• Output: SETTrackerHits _SITTrackerHits_ VTXTrackerHits
