These track methods (G4Track::GetTotalEnergy, GetMomentum) seem to both return in units of MeV.
However, they do not seem to agree with each other.
Here is an example, when both of these are called on the same track: ParticleName: e- TiD 1 Momentum: (1.2935833,-19.454915,3.1657942) Energy: 19.759819
The magnitude of momentum is: 19.753210582789258
This is about .03% off the energy.
Is this because energy and momentum are actually reported for slightly different times, even though I am calling them one right after the other in the code?
