I took a recent run 173019
The first plot is the adc distributions
and the second the cluster. this is the itpc region. for itpc sector 3.
You see that whenever there is a single dead channel is seems to affect 
regions in the same row
by reduced intensity.
Is this also seen in fastoffline? I guess whats shw there is hit 
distributions on track?
This pattern is consistently seen over different sectors.

I can understand there is reduced effenciency for clusters with the 
nominal cluster width in pads (3-5 pads) buts this seems to extend much 
further.
