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

The angle is (0, 360).

Same table as above but with the cut 1.0 < W < 1.5

Insert the same table as above but with the cuts 1.0 < W < 1.25 GeV

Same table as above but with the cuts 1.0 < W < 1.5 GeV and -0.2 < [math]cos\theta_{pion}^{CM}[/math] < 0

I have applied the cut only on [math]cos\theta_{pion}^{CM}[/math]: 0.4 < [math]cos\theta_{pion}^{CM}[/math] < 0.6.(I know it does not look as good as it should be.)
