All plots are generated with T2 triggers and cut off edtm pulser.
1. Total energy deposited (sh+ps) 2. Preshower energy 3. Preshower vs shower 4. Preshower vs shower during transversity (run 5866)
Shower threshold for T2 is set 500MeV which was close to what it was on T6(~450MeV) during transversity.
The correlation between Ps and Sh (plot3) energy doesn't look the same as transversity run (plot4). There are lot more events with low energy in shower when there is high energy deposited in pre-shower. I would expect a large pre-shower signal to show a large signal in shower too, most of the time(for electrons).
