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