The perturbation parameter in the lopsided potential obtained by the analysis of the kinematic data  ⟨ ϵ_kin ⟩  vs. the one obtained from the morphological data  ⟨ ϵ₁ ⟩ . The symbols represent the five kinematic classes defined in Paper I. Type 1: receding/approaching sides agree on all scales (solid triangles); type 2: constant offset of receding/approaching sides (solid squares); type 3: differences only at large radii (open triangles); type 4: differences only at small radii (open squares); type 5: receding and approaching sides change sides (stars).
