[G14_run] mmass vs polar angle

[Eugene Pasyuk]

Hi Irene, 

Looks nice. A couple of questions. 
For which particle is this angle or you put both pion and proton angle in the same histogram? Is it the lab angle or center of mass angle? It would be good to see this in a lab frame separately for pion angle and for proton angle. Can you do this? 

Thanks, 

-Eugene
