Single π+ Track
= Single π+ Reconstruction (trackeff_hists plugin)
- The below plots show the track reconstruction efficiency and resolution using the single-track scripts plugin (trackeff_hists).
- However, this efficiency is extremely misleading:
- If a track is reconstructed using any of the hits that were on the thrown track it is considered "found."
- This is regardless of whether the reconstructed track momentum is anywhere close to the thrown values.
= Single π+ Reconstruction (NEW trackeffv2 plugin)
- The below plots show the track reconstruction efficiency and resolution using a new plugin (trackeff_hists).
- This plugin compares matches all of the thrown and reconstructed particles in the event, and requires that their momentum be "close."
- "Close" for track candidates is defined as: Δp/p < 20%, Δθ < 40 degrees, Δφ < 40 degrees, ΔVertex-Z < 1 km
- For thrown tracks with θ < 5 degrees, there is no cut on Δφ
- "Close" for time-based tracks is defined as: Δp/p < 10%, Δθ < 15 degrees, Δφ < 15 degrees, ΔVertex-Z < 10 cm
- "Close" for track candidates is defined as: Δp/p < 20%, Δθ < 40 degrees, Δφ < 40 degrees, ΔVertex-Z < 1 km
