Inclusive electron scattering

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 spane 25 +/- 15

File:TS NoSolGcard 022916.txt

File:TS SolGcard 022916.txt gcard for Solenoid

Solenoid Off

Why is efficiency grater than 1?

Why is their a discrepancy between the number of events in solenoid vs no solenoid? I ran 975,000 events for both.

Reconsstruction efficiency

Generated with no solenoid.	Reconstructed with no solenoid.	reconstructed divided by generated with no solenoid.

Solenoid On

Reconsstruction efficiency

Generated with solenoid.	Reconstructed with solenoid.	reconstructed divided by generated with solenoid.

Ratio Solenoid Off / On

No solenoid reconstructed divided by solenoid reconstructed.

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.
