     Which factor? What line of the code? I haven't looked at this code
    since Dec., but I think, everything was correct back then... Just tell
    me, I'll check.
    
     BTW, I tried centrality 6% cut based on ZdcAdcSum vs. BigBBMultiplicity
    and it works surprisingly good! It is absolutely vertex independent and
    for narrow vertex cut agrees pretty well with Tiles 6% Centrality cut,
    based on JH's code. Now I can produce dN/dEta information for huge
    vertex (eta) range and it looks nice. I'll try to wrap it up in a first
    approximation, check for bugs and produce some kind of a note about that
    in couple of days.
    
    					Thanks,
