Spiral Fitting - Viewer Comparison
- Notes:
- All events have one π+ thrown at p = 150 MeV/c, θ = 90 degrees, φ = random.
- Current Code = Code as of 04/08/12
- Current Code # Reconstructed Track Candidates in events below: 4, 6, 5, 12
- Spiral Code # Reconstructed Track Candidates in events below: 2, 1, 0, 1
- Event 1: Spiral Code reconstructs two tracks due to turn near beamline, will be difficult to reduce to one track.
- Event 2: Spiral Code reconstructs both spiral arms (from the beamline to the edge) and then links them together to form one track
- Event 3: Not sure yet why spiral code fails to reconstruct anything.
- Event 294: Current code ignores stereo hits while trying to link axial hits together by phi: explosion in track candidates
- Event 294: Spiral code has memory explosion (leak?) while attempting to link axial and stereo hits together, need to improve somehow...

Spiral Fitting - Procedure Overview
- Link adjacent hits together within each superlayer
- Link adjacent superlayer hits group together (all possible combinations)
- Fit the axial superlayer hits (and the beamline) to a circle (for each unique axial group combination)
