Dear Dávid,
Thank you for your answer!
Indeed, the WHAT(3) in ROTPRBIN removed the zero events. One last thing: is it possible to completely remove the messages of the form
Binning n: 1, "De19 ", Event #: 1, Primary(s) weight 1.0000E+00
Number of hit cells: 1
for all events? To get a raw column of data? Just to avoid offline processing.
Thank you very much once again!
Cheers,
Federico
