Cuts

[math]EC_{tot}\gt 0.2*p[/math]


Etotal over P using tot cut.gif
Without any cuts we have 181018 entries. After using the following cut [math]EC_{tot}\gt 0.2*p[/math] we are getting 127719 entries, which is about 70.55% of 181018.

[math]EC_{inner}\gt 0.08*p[/math]

After the cut on the energy deposited into inner part of electron calorimeter, number of entries decreases by 22%.

Both cuts are applied

In case of using the cuts of the total deposited energy and the enregy deposited into inner calorimeter number of entries decreases ~36%
