Reconstruction efficiency

Reconstructed with solenoid	Reconstructed with no solenoid	solenoid off divided by solenoid on

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

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.

Reconstruction efficiency

Generated with no solenoid. 824,979 Events	Reconstructed with no solenoid. 609,106 Events	reconstructed divided by generated with no solenoid 200 Bins, 40 Bins.	Zoomed in version of the efficiency.

Solenoid On

Reconstruction efficiency

Generated with solenoid.	Reconstructed with solenoid.	reconstructed divided by generated with solenoid. 80 Bins, 20 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.

Ratio Off/On

Bins 400 x 50.	Bins 3 x 1 .

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.
