Hi Andrei,

This is just my 2 cents worth from a users point of view.

1) I had this problem too. Given the question, I presume that you
are running within JAS3 and have done the compile/load/go
cylce twice. When you do this, JAS3 does not delete/reset
the histograms between runs. There is a way to reset them
that I forget because I do not run within jas3. In the worst
case, exit and restart jas3.

2) The official example of accessing hits is:
http://confluence.slac.stanford.edu/display/ilc/Accessing+Si mTrackerHit+information
This gives you access to SimTrackerHits which are intersections
of a track with a sensitive volume.

At present there is no standard way to access information about hit
strips or clusters. Nick, Tim, Dima and Hans have all done work but it is all in their contrib areas. I have to run now but will send more information later.
