Macros

• run_reco_experiment.C: version is stamped in the reconstruction file name.
  Ex) run3000_s0.reco.v1.03.root

Reconstruction

• Pre-vertex finding is added in track finding step. This is used to recognize:
  • charge of the particle by calculating rotating direction and
  • direction of track. (Direction of the track was opposite half the time in the previous version)
• STTrack
  • If STVertex(primary vertex) is found and track is used to find it, STTrack::GetParentID() gives 0.
  • STTrack::GetVertex() gives closest extrapolated position to primary vertex (if STVertex is found).
  • STTrack momentum vector is calculated at STTrack::GetVertex() (if STVertex is found).
  • Also momentum vector is always set to z > 0. This is temporary solution for finding direction.

Event Display

• Different charged particle track has different color.
  • red: positive
  • blue: negative
  • gray: not fitted or not primary track.
