Comparison of the single leptons distributions for LVL1 and LVL2 evetns with separation for systems

Comparison of momentum distribution of single leptons separetely for system 0 and 1 and polarity

Comparison of azimuthal angle distribution of single leptons separetely for system 0 and 1 and polarity

Comparison of polar angle distribution of single leptons separetely for system 0 and 1 and polarity

Table below shows the eficiency of the LVL2 trigger as a function of p, theta, phi for sys0, sys1 and both systems together.
Efficiency is calculated in this case as a ratio of the integrals from the distributions presented above.

		sys0	sys1	both sys
	phi	51%	83%	75%
	theta	51%	83%	75%
	p	51%	83%	75%

As one can see the efficiency in the TOFino/PreShower (sys0) is much lower then in the TOF (sys1).
This observation is know, it is a side effect of the wrong maping in the PreShower detector.
