Hi,

So what i have done is to run simulation (pgun) for positrons with the momentum
range 0.15- 5 GeV/c . For one of the event, e.g. 246, simulations takes 6 minutes.
This is not the worst case of event. Here is printout which i'm getting on the scream.
in addition i'm attaching plot which is showing amplitude of the sample: PndTpcSample.famp()

Hope it will help you, i can also plot different distributions, but it would be nice
if you would be more exact what to plot.

best regards,
