Inclusive electron scattering
Sweet spot
Send electrons only at the center of a single sector.

Inclusive Track Reconstruction efficiencies
Plot the reconstruction efficiency for an electron as a function of the angles Theta and Phi
I used the following: UBUNTU 14, coat-java-1.0
No Solenoid gcard:
angle spans 25 +/- 15

gcard for Solenoid
Solenoid Off
Question for Same Number of Events ran:Why is their a discrepancy between the number of events in solenoid vs no solenoid? I ran 975,000 events for both.

| Generated with no solenoid. 824,979 Events | Reconstructed with no solenoid. 609,106 Events | reconstructed divided by generated with no solenoid 150 Bins, 15.0 Bins. | Zoomed in version of the efficiency. |

| Generated with solenoid. | Reconstructed with solenoid. | reconstructed divided by generated with solenoid. 60 Bins, 5.0 Bins. | Zoomed in version of the efficiency. |
Ratio Solenoid Off / On
NOTE: The reason the division is at around 5 is because for some reason there were 5x the amount of no solenoid events vs solenoid events. I ran 975,000 events for both no solenoid and solenoid, but a reasonable ~500,000 came out for no solenoid. For some reason only ~100,000 came out for solenoid.
directly divide reconstructed solenoid off by reconstructed solenoid on
No solenoid reconstructed divided by solenoid reconstructed.
directly divide reconstructed solenoid off by reconstructed solenoid on that has been multiplied by (825/150)
Phi angle shift
Phi angle Solenoid on - off difference
spread from 0 to 5 GeV.
Observations
Why does the Solenoid off events only extend to 25 degrees whereas the solenoid on go to 40.
