keyword=scintillator efficiency for coin13_he4
Below are two plots from good ent_type and "junk" ent_type, from which we can estimate the upper limit of the scintillator inefficiency.
From these plots, I did not any apparent dependence of the inefficiency on the coordiante x.
cuts used:

Figure 1:
above: abs(rs1x)<1.0&&abs(ent_type-1)<0.5
below: abs(rs1x)<1.0&&abs(ent_type-2)<0.5
Figure 2:
above:abs(ls1x)<1.0&&abs(ent_type-3)<0.5
below:abs(ls1x)<1.0&&abs(ent_type-4)<0.5
