Update
- 1234 segmentation now an option in reconstruction code
- New algorithm comparable to or better than KLOE algorithm in every test I tried
- Will be checked in soon
Changes
- More flexible DBCALGeometry allows 1234 summing (checked-in)
- Change weighting when averaging quantities to form cluster
- Improve error estimation
- Tune parameters
- Fix various bugs
- Change in KLOE algorithm to min energy threshold of cluster to make the two algorithms match
Single photon event sample
45000 events, energy uniformly distributed from .05-2.05 GeV, angles from 10.8-118. Exclude all events with tracking hits, since we can't expect to reconstruct a photon in this case. All results with 1234 summing.
Efficiency
Both algorithm have ~99.5% efficiency.
Energy resolution
These plots use E_raw, not the corrected/calibrated E.
