Dear all,

After looking into a pusher code I realized that the relativistic
correction is applied during the new momentum calculations. So my
question is irrelevant.

Initially I got confused by the BinEnergyParticles.hpp file where there
are two branches of code for energy: relativistic and non-relativistic.
I guess the non-relativistic case represents a limit of low gamma (while
the momentum is kept to be relativistic)  and introduced for the sake of
accuracy.



Thanks,

Danila.

Dear all,

I have a bit naïve question regarding data in h5 files for the version
0.2.2. Am I correct that the moment of particles saved in simulations
dumps is not relativistic corrected?

And then if I want to calculate the kinetic energy histogram, for
instance, I need to calculate gamma manually? There is a plugin to
calculate energy histogram while simulation is running. However I wasn’t
using it, so I need to calculate it during my post-processing.



Thanks,

Danila.
