Correlation plots with[math]cos\theta_{pion}^{CM} , W[/math] , and [math] Q^2[/math]

The angle is (0, 360).

[math]cos\theta_{pion}^{CM}[/math] vs [math]\phi_{diff}^{CM}[/math] [math]W[/math] vs [math]\phi_{diff}^{CM}[/math] [math]Q^2[/math] vs [math]\phi_{diff}^{CM}[/math]
Pion cos theta in cm frame vs phi angle difference in cm frame with cuts.gif Missing mass vs phi angle cm frame.gif Q sqrd vs phi angle cm frame.gif



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

[math]cos\theta_{pion}^{CM}[/math] vs [math]\phi_{diff}^{CM}[/math] [math]W[/math] vs [math]\phi_{diff}^{CM}[/math] [math]Q^2[/math] vs [math]\phi_{diff}^{CM}[/math]
Pion cos theta in cm frame vs phi angle difference in cm frame Wlt1.5.gif Missing mass vs phi angle cm frame Wlt1.5.gif Q sqrd vs phi angle cm frame Wlt1.5.gif 


Insert the same table as above but with the cuts 1.0 < W < 1.25 GeV
[math]cos\theta_{pion}^{CM}[/math] vs [math]\phi_{diff}^{CM}[/math] [math]W[/math] vs [math]\phi_{diff}^{CM}[/math] [math]Q^2[/math] vs [math]\phi_{diff}^{CM}[/math]
Pion cos theta in cm frame vs phi angle difference in cm frame Wlt1.3.gif Missing mass vs phi angle cm frame Wlt1.3.gif Q sqrd vs phi angle cm frame Wlt1.3.gif


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

[math]cos\theta_{pion}^{CM}[/math] vs [math]\phi_{diff}^{CM}[/math] [math]W[/math] vs [math]\phi_{diff}^{CM}[/math] [math]Q^2[/math] vs [math]\phi_{diff}^{CM}[/math]

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.)
