Mattione BCAL Segmentation

Procedure

(genning very forward) Fit current BCAL time uncertainties for photons, pions, and protons: make sure they're similar to the uncertainties in David's studies.
- If they are not: probably due to clustering algorithm(s): ASSUME that the % of the timing uncertainty improvement is independent of this difference.

(Waiting on results) Fit the BCAL time resolution improvement % from the table of David's results as a function of theta (separately for photons, pions, and protons). Energy-dependence comes from the coefficients.

(genning very forward) Separately generate single-track events of photons, pions, and protons with the BCAL time smearing disabled (generated at center of target: assume that this is what David did).
(Plugins running (photon, piplus done, proton genning group 2), merge trees) Determine time-smearing necessary to reach the improved time resolution, code smearing into BCAL shower reconstruction.

Determine PID cuts for protons & pions (delta-beta vs p) for both smearing resolutions (use datasets generated earlier).

(Running) Generate b1pi events (all vertex z)
Two analyses: one with BCAL time smearing disabled (smear during shower reconstruction), the other with default smearing.
Run cooking code to reconstruct events.
Perform b1pi analysis, using PID cuts (allow all hypotheses).
