- Fixing pluralization of table names in DataModel. This was silently introducing an error in AO2D merging, due to the previous way my local aod-writer was written. Now fixed using local o2-aod-merge…

- Implementing QA plots to understand (and find a way to minimize/remove the effects of) the "Azimuthal Efficiency Effect" (AEE), which is the main source of fake polarization signal -- caused by rec…

- Renaming histograms and adding "forceRandJet" options. As the Azimuthal Efficiency Effect (AEE)'s fake polarization signal is inherent to the Lambdas themselves and the magnetic field, randomly cha…
