Phi_angle_in_CM_Frame for different [math]cos\theta_{pion}^{CM}[/math] cuts
Used 1735 files. The following cuts are applied: [math]0.9\lt M_x\lt 1.1[/math], [math]1.1\lt W\lt 1.5[/math] and EC cuts.
Insert plot of M_x and W to show cuts
Then insert phi -vs- theta
Cuts: EC_inner>0.06, EC_tot/p>0.2, nphe>2.5, [math]0.9\lt M_x\lt 1.1[/math], [math]1.1\lt W\lt 1.5[/math] and [math]0.6\lt cos\theta_{pion}^{CM}\lt 0.8[/math].
