Summary
- BCAL reconstruction seemed to be an obstacle in b1pi events
- Two reconstruction algorithms in tree: KLOE algorithm=default, "new" algorithm by matt s.
- Found two issues which lead to poor energy resolution at low E (fixes not checked in yet)
- "New" algorithm seems to be doing well, at least for single-photon events
- Further fine-tuning needed, but maybe should wait until BCAL segmentation finalized?
- Further study of b1pi, etc.
