Track Candidate Reconstruction Sampling

  • All events have one π+ thrown at p = 150 MeV/c, θ = 90 degrees, φ = random.
  • These are identical to those presented at the 04/25/2012 Tracking Software meeting.

Spiral Fitting - Histograms

  • # Reconstructed Tracks / Event:
    • NOTE: Hit selectors disabled for wire based & time based fits: just use hits from track candidates (and ignore hits after spiral turn back inwards)
Track Candidates
Wire Based Tracks
Time Based Tracks


  • Track Candidates: Track Parameter Differences (BEST Reconstructed - Thrown)
    • Best Reconstructed = Track Candidate that is the closest match to the thrown track.
    • NOTE: Δφ = 20 not real, due to artifact: reconstructed track candidate parameters are reported at a point along the track (~)just outside the start counter, whereas thrown parameters reported at thrown vertex (beamline)
    • Need to work on θ reconstruction.
