Hello,

Is there any way to control the accuracy of the integration?

I get about a 2 degree difference from an analytical solution for a field of ~0.6 Tm and 300 MeV momentum, in a constant field.

I tried to use almost all the integrators (at least the ones that should be potentially more accurate than ClassicalRK4), and they all perform the same or worse than ClassicalRK4. Step size does not seem to affect it either.

Thanks in advance.
