Computation of the "SubhaloVmax" and "SubhaloVmaxRad"

Dear TNG team,
I have a simple question regarding the "SubhaloVmax" and "SubhaloVmaxRad" in the halo catalog. These are variables extracted from the rotation curves. In hydro-simulations, are these rotation curves computed considering all components or the dark matter only?
Thanks,
Daneng

These are always computed using all mass, i.e. particles/cells of all types.
If you wanted a DM only calculation, you would have to compute this separately.

I will clarify the documentation.
I see. Thanks for the clarification.
