It's possible ... I asked the Geant collaboration to add this code, so I'm responsible for any bug is this piece of code. Before 4.9.2.p02, the whole beta x E terms was missing. I could have screwed it up. It's been a while since I wrote this, so let me trace back through what I did and see how the argument went....

When you say the "simulated spin rotation frequency do not agree with the correct frequency from Thomas-BMT equation", did you check that? Are you sure the C is not hiding somewhere else? Are you sure you're using the Maxwell equations in the right units? I cribbed most of the equations from Jackson, 2nd edition, and matched them onto the existing code to try and get the units right.

I'm not sure I got it all right, but it would be nice to do so before I need to start relying on my own simulation results :-)
