Reconstruction To Do List

Generation
1. Use genr8 for a2 production
2. Use Pythia for background generation after removing a₂ → η π⁰ from the MC data stream
3. Use a2 charge exchange production xsection vs pythia total xsection to estimate number of signal and noise events
4. Skim off (hd_filter) the wanted events by cutting on the total neutral energy (> 6 GeV) but record the total number of events before skimming
Analysis
1. After pruning the Pythia events, check the generated vs. reconstructed energy in a plot.
2. Look at the a2 mass peak - adjust cuts on the eta and pi0 masses then look at the effect on the different angular distributions (i.e. Gottfried-Jackson angles, etc.)
3. look at difference between reconstructed and generated z position for less than 65 cm
4. look at single photon reconstruction efficiencies
5. adjust the error matrix for the BCAL (look in PID/DPhoton_factory.cc)
Gather all relevant DocDB documents and cross section publications at one spot on the Wiki.
