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

Insert the same table as above but with the cuts 1.0 < W < 1.25 GeV
| [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/math] | [math]\displaystyle{ W }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/math] | [math]\displaystyle{ Q^2 }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/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
| [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/math] | [math]\displaystyle{ W }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/math] | [math]\displaystyle{ Q^2 }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/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.)
