Correlation plots with[math]\displaystyle{ cos\theta_{pion}^{CM} , W }[/math] , and [math]\displaystyle{ Q^2 }[/math]
The angle is (0, 360).
Same table as above but with the cut 1.0 < W < 1.5
Same table as above but with the cuts 1.0 < W < 1.25 GeV , 20 MeV bins in W and 15 degree bins in [math]\displaystyle{ \phi }[/math]
Same table as above but with the cuts 1.0 < W < 1.5 GeV and -0.2 < [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] < 0
Insert the same table as above but with the cuts 1.15 < W < 1.25 GeV and -0.1 < [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] < 0, 20 MeV bins in W and 15 degree bins in [math]\displaystyle{ \phi }[/math]
Insert the same table as above but with the cuts W < 1.25 GeV and -0.1 < [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] < 0, 20 MeV bins in W and 15 degree bins in [math]\displaystyle{ \phi }[/math]
Phi_angle_in_CM_Frame for different [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] cuts
Used 1735 files. The following cuts are applied: [math]\displaystyle{ 0.9<M_x<1.1 }[/math], [math]\displaystyle{ 1.1<W<1.5 }[/math] and EC cuts.
Insert plot of M_x and W to show cuts
Then insert phi -vs- theta
