Difference: HighPtIsEMStudy (r4 vs. r3)

Important steps

1. Having a code working on data and MC. Integrating GRL and trigger information.

2. Being able to match data/mc for all variables or at least main shower shape variables.

3. Do studies on isEM variables and cuts (in order to improve isEM for high PT electrons)

Help optimizing (efficiency, rejection) electron identification (from electron candidates in the Electron Container) for electrons with very high pt. The electron candidates in the ESD have passed the three trigger stages and undergone offline reconstruction/reprocessing.

4. Do trigger efficiency studies with Tag And Probe (possible to extrapolate?)

  1. Which Trigger?
  2. How to include?
