---+++ 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. %BR%
Efficiency is calculated in this case as a ratio of the integrals from the distributions presented above.%BR%

||      | *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). %BR%
This observation is know, it is a side effect of the wrong maping in the PreShower detector. %BR%
