ECAL Calibration Tasks

Alignment

Alignment

- based on survey

- based on tracking
Energy

- FEE
  - absolute
  - dedicated FEE runs and singles triggers
- Møllers and WABs
  - absolute
  - 4.4 GeV and positron trigger should greatly reduce their statistics/usefulness
  - singles and old-pair triggers may help
- Cosmics
  - relative, before and after the run
- LED
  - relative, before and during the run
- Edge corrections
  - based on tracks' y-intercept at ECAL relative to ECAL y-edge
Time

- channel offsets

and

- time-walk

these presumably haven't changed significantly since the 2016 run

- RF
  - signal shape is different relative to 2016
  - potentially more important for positron/singles triggers than for pairs
