Fig. 2.

Velocity distribution in spherical polar coordinates (V_r, V_ϕ, and V_θ are the radial, azimuthal, and polar components, in km s⁻¹) of the VOD and HAC. Upper panels: scatter diagrams of the velocity distributions of the VOD (black) and HAC (red). Lower panels: histograms displaying the velocity distributions of VOD (black) and HAC (red) members.
