Phi angle in CM frame for different runs
EC_total, [math]\displaystyle{ cos\theta_{pion}^{CM} }[/math] vs [math]\displaystyle{ \phi_{diff}^{CM} }[/math], missing mass, [math]\displaystyle{ \theta_{e} }[/math] vs [math]\displaystyle{ \phi_{e} }[/math]
- Electron Momentum vs EC_total
- Missing Mass
- [math]\displaystyle{ \theta_{e}^{LAB} }[/math] vs [math]\displaystyle{ \phi_{e}^{LAB} }[/math]
[math]\displaystyle{ \varphi^{LAB} }[/math]
The angle is (0, 360).

[math]\displaystyle{ \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
| [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

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.)
