- Blake's Analysis: Blake walked us through his initial analysis on the ADC calibration using the MC. There's a hump at low values (~channel 200) in the individual cell spectra, adding up to a hump in the summed ADC (North and South). This is affecting the MeV/channel calibration. Cutting the hump improves the fits. The problem does not seem to be related to the pedestal subtraction. All these plots are from Run 2334 (our nominal run).
- Investigate the origin of the hump.
- Use timing information in this search (Blake).
- Add VETO to dst ROOT trees (David by end of week).
