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.
Event # | Hits (CDC & Truth) | Current (04/08/12) Code Track Candidates | Spiral Code Track Candidates |
---|---|---|---|
Event 1 | |||
Event 2 | |||
Event 3 | |||
Event 294 |
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: 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.
