Is vel_x provided in the Subhalo Details for each subhalo the bulk (center) velocity? How is it calculated ?based on the galaxy center defined by the minimum potential?
Thank you so much.

In the documentation you can find this sentence, about the fields available for subhalos in the API:
"All Subfind group catalog fields are given, flattened into separate values if a vector, and with modified names. In particular, the 'Subhalo' prefix is removed. For values by type, the 'Type' postfix is removed from the end of the name and '_gas', '_dm', '_stars', and '_bhs' added. For 3-vectors, '_x', '_y', and '_z' are added. For example, SubhaloPos becomes pos_x,pos_y,pos_z. "
So vel_x follows exactly the definition of SubhaloVel in the documentation.
