Unit of curved path CTRACK

Scoring
1

Dear Experts

Im running a userdump with boundary crossing in a geometry with enabled magnetic fields.
In the collision tape I’m scoring the variable CTRACK=curved path.
What is this variable and what is the unit?

In my analysis I found that also photon and neutrons have a distribution of curved path values.
Should the values be 0 (or at least a constant) as neutral particles don’t get deflected in a magnetic field?

It’s the length of the last step in cm and applies to any particle. The path is curved only for charged particles in magnetic/electric field.
