Dear all, <= /span>

After looking into a p= usher code I realized that the relativistic correction is applied during th= e new momentum calculations. So my question is irrelevant.

Initially I got confus= ed 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 t= he sake of accuracy.

Thanks,

Danila.

Dear all,

I have a bit na=EFve question regarding data in h5 f= iles 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 h= istogram, for instance, I need to calculate gamma manually? There is a plug= in to calculate energy histogram while simulation is running. However I was= n’t using it, so I need to calculate it during my post-processing.

Thanks,
