keyword=E/P for kin 6.23: high pions run
From run# 2943: E=4.21 GeV, E'=1.169 GeV, W= 2.556 GeV.
Using the same calibration, the figure 1 gives a idea of the pion contamination at the lowest momentum of energy 4.21 GeV running.
The green curve is still with anti-cerenkov cut and the red one with cerenkov cut.
The second picture is with cerenkov cut.
