The FLE thresholds defined for 1/4 of all calorimeter channels from this 5 min run shown on the following plot
Thersholds form rather narrow peak at 140 MeV, but it is biased with respect to expected threshold value 100 MeV for this configuration
I made the same analyze and I've got the same results, except for the FLE threshold at 158 MEV. this should be due to a difference due to the fit procedure.
FLE thresholds for CAL all channels for low setting
FLE thresholds for CAL all channels for high setting
