Sergey:

Andrey reported the problem based on the MC files produced by Yehor using EPOS (Pb+Pb 30 2016):

 in the plot PSD energy vs impact parameter, there is a cloud at large b and small E_PSD (see slides in one of the previous meetings).

Sergey, using the EPOS generator, does not see the cloud. Thus, there is a disagreement between Yehor and Sergey's results.

We need to check the configuration and log files.

Maja's suggestion: PSD position?
