Track Candidate Reconstruction Sampling

• All events have one π⁺ thrown at p = 150 MeV/c, θ = 90 degrees, φ = random.

Performance

• 1000 events, all with one π⁺ thrown at p = 150 MeV/c, θ = 90 degrees, φ = random.

Multiplicity

• # Track Candidates

Current (08/20/13) Code

Spiral Code

• # Time-Based Tracks (with PID = π⁺)

• Average Event Reconstruction Rate:
  • Current (08/20/13) Code: 7.5Hz
  • Spiral Code: 17.5Hz

Accuracy

•  % of events with at least one track that is "roughly close" to the thrown parameters:
  • "Roughly Close": p within 20%, θ within 15 degrees, φ within 30 degrees, Vertex-Z within 10cm
