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

The angle is (0, 360).

I have applied the following cuts: EC_tot>140MeV, EC_inner>50Mev and nphe>2.5.

phi_angle_in_cm_frame_vs_electron_sector

9 files. The cuts: EC_tot>140MeV, EC_inner>50Mev and nphe>2.5.






phi_angle_in_cm_frame_vs_electron_sector

I used 27 files. The cut is applied on [math]\displaystyle{ 1.6 < Q^{2} < 1.9 }[/math].
