ρ events
- Generated 100000 events with genr8
- Require pπ+π-, each with tracking CL>0.001
- Use default PID algorithm
- 4C kinematic fit (nothing missing)

b1π events
- Generated 100000 events with genr8
- Require p2π+2π-, each with tracking CL>0.001
- Use default PID algorithm
- 1C kinematic fit (missing π0)
Missing mass squared for the reaction γp->p2π+π-(X). Red histogram is after cutting on CL from kinematic fitting at 0.01.
Black histogram uses momenta from tracking reconstruction; red histogram uses refined momenta returned by kinematic fitting code
