Hi YT users,
I would like to make a (spherical and/or cylindrical) profile of the velocity dispersion.
In order to do so, I need to compute the mean velocity (BulkVelocity)

velocity dispersion field, and then make a profile for the velocity
dispersion field.
Is there a particular way in yt to handle this?
