Fig. 2 preshower software sum vs total shower hardware sum (shower is off)
Observation, for the preshower, 0-16 channels has a split in the hardware sum compared to software sum. The 17-25 channels do not have this feature, but clearly hardware sum is lower than the software sum. The split is corresponding to the hit at different side of preshower counter.
