Watching this plot of the events in function of eta and phi, we found that the eta shifter was not working properly.
As you can see the selected region (green) in eta is from -1 to 4, but in cfg file we selected 0 to 4... so etaShifter considered 0 as -1. This is now fixed.
We still have a problem, this assert: assert ((m_etaEnd-m_etaStart)%m_etaWidth == 0) ;
fails if the 0 cristal is included in the eta interval... so this has to be fixed. Right now the solution is to not include 0! ;-)
Another nice plot...
