Hi Yuri,

Question: is it the low cut or the high cut that caused this difference. 
It would be good to see the typical distribution of the cluster sizes. 
At least looking at the online plots
the typical cluster witdh i.e integrated over all events peaks at 
width=4 with only little and clearly a high tail.below. Of course this 
can be different for highly ionizing particles.
