I am looking at the clusters in TNG-cluster, and I found on the page that one cluster, https://www.tng-project.org/api/TNG-Cluster/snapshots/99/subhalos/00000000/
There is called "vmax", Does that mean I can use this "vmax" as the Vmax of this cluster? which object of this value of this "vmax" is given?
Or do I need to re-calculate the vmax by myself using all particles belonging to this given cluster?
Looking forward to your reply

All fields available on the API (including "vmax" as you discuss here) are the same fields as available in the subhalo catalog.
The definition of SubhaloVmax is "Maximum value of the spherically-averaged rotation curve. All available particle types (e.g. gas, stars, DM, and SMBHs) are included in this calculation."
As with all subhalo quantities, this means it is calculate using the particles of that particular subhalo.
if this is what you want, then you can use this value, otherwise it would probably be best to calculate exactly what you want.
