This is an illustration of improvement of MIP finding efficiency if ADC gates are set on BPRS & BTOW at the places matched to actual gains instead of  fixed 'ideal' location.

Jigsaw Inv Mass Plots (final)

 As noted here and here, the pion peak is difficult to model using single-particle MC.  In single particle studies, the pion inv mass peak is reconstructed to narrow.

BEMC Related Studies

My initial attempt at pinpointing the causes of the 'floating' pion mass examined, as possible causes, the fit function, an artificial increase in the opening angle, and the BEMC energy resolution.
