if you look at the *sum.lis file produced by postprocessing, you will find
there already the integral value (integrated over energy and angle). For a
double differential plot, instead, you do not want to renormalize by the
energy and angle bin widths. For a single differential one (in energy),
the renormalization is just by the angular range and it is already
provided by postprocessing, to be plotted in Flair.

This further normalization is done already by FLUKA only if you input the
area of the boundary surface in the USRBDX card. Otherwise, you can do it
yourself afterwards, as you wrote below it's just a trivial multiplication
(moving from particle number - weighted by the angle cos - to actual
fluence in cm-2 - thanks to the weight above already embedded in the
number -).

YES.
