Goals for Calorimetry Group

1. Determine preliminary photon reconstruction efficiencies as a function of E, phi and theta in data and simulation with a point-to-point precision of at least 5%.
2. Measure systematics of pi0/eta mass calibration as a function of detector position to a precision of at east 5 MeV.
3. Demonstrate agreement of photon reconstruction efficiency and resolution between data and simulation as a function of E, phi and theta to within 5%.

Action Items

1. Check switches on FCAL board with high scaler rates and make sure it is set to 2 V full scale. (Colin and Sasha)
2. Move monitoring plots of the FCAL/BCAL front panel triggers into FCAL/BCAL monitoring section (Zisis)
3. Complete calibrations by April 1? See 2020 Data Production
