Phi angle in CM frame for different runs

EC_total, [math]cos\theta_{pion}^{CM}[/math] vs [math]\phi_{diff}^{CM}[/math], missing mass, [math]\theta_{e}[/math] vs [math]\phi_{e}[/math]

[math]\varphi^{LAB}[/math]

The angle is (0, 360).

[math]\varphi^{CM}[/math]

The angle is (0, 360).

I have applied the following cuts: EC_tot>140MeV, EC_inner>50Mev and nphe>2.5.
