USRBIN: Average or Cumulative Score?

Dear all,

Say I run a simulation over 10000 histories. At the end of the run, does USRBIN (irrelevant of the type of binning or whether it’s region scoring) give the average over 10000 histories or the cumulative over 10000 histories please?

Thank you :slight_smile:

Dear Ryan,

the FLUKA results are always the averaged value for one primary (weight). To get the statistical error, you need to run multiple cycles with approximately a similar number of primaries.
