[SBS_sim] Replay with fewer planes

[Bogdan Wojtsekhowski]

Hello Ole,

I would guess that such a result indicates a strong
correlation between data in planes. Much stronger
than suppose to be for low energy background.
I will advicate to look the single event:
amplitude vs strip number on each readout plane.
