PID from readout scheme

Two readout seems are looked at:
a) 1,2,3,4
b) 3,3,4
The numbers indicate how many SiPMs are summed together into one digitization channel.

Neutron/Photon separation

In the following plots the vertical axis is probability and the horizontal axis is
a) 1/(4) : one cell out of four
b) 2/(4) : two cells out of four
c) 3/(4) : three cells out of four
d) 4/(4) : four cells out of four
e) 4th only : only fourth cells out of four
f) 2/(4) : two cells out of four with gap in between the two
