Comparison of integrated velocity dispersion profiles for spheroids identified using the six different methods of dynamical decomposition as a function of the 3D radius r of the IllustrisTNG galaxy. Top panel: Comparison of the radial integrated velocity dispersion profiles σ_r(< r). Middle panel: Comparison of the azimuthal integrated velocity dispersion profiles σ_ϕ(< r). Bottom panel: Comparison of the polar integrated velocity dispersion profiles σ_θ(< r). In all cases, the profiles corresponding to the original spheroid are indicated with a black solid line.
