Solenoid Off

Why is efficiency grater than 1?

1.5_NS.ev could not be reconstructed 3.75_NS.ev could not be reconstructed

~150,000 events missing in the No Solenoid reconstruction, but because both generated and reconstructed are in the .evio file this would not have affected the efficiency for the no solenoid. This would have affected the ratio of off/on reconstruction because the sample sizes would be off by a significant amount.

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.
