Selection of the elastic events has applied done on the following distributions

175 < delta_phi < 185
tanTheta*tanTheta > 1
pion and proton identification via cuts on mass

Overlay of ppi- missing mass^2 from PE (blue line) target and C (red line) one.

Spectra are normalized to yield in the ragio far from the peak position.

Non-elastic events

Overlay of ppi- missing mass^2 for non-elastic events from PE (blue line) target and C (red line) one.

Spectra are normalized to yield in the ragio far from the peak position.
