Thank you for responding to my question.
What I want is the momentum direction the track had at the start of the track (e.g. at the vertex), not for a given step.
In any case, no matter where I get it from, for the physics I am looking at, the momentum distribution should be isotropic; Very low energy -> no boost and capture at rest on top of that ...
I spent the better part of the day, trying to find other ways to implement my physics, but to no avail ... something is fishy ...
For now, I am resorting to reassigning a new momentum direction in tracking action, which I find rather unsettling.
