Top: asymmetry measures of the  ⟨ k₅/k₁ ⟩  term and velocity dispersion as derived from the MC realizations for the four objects. For each source, 150 MC simulations are run but the  ± 3σ results are shown. The solid red line indicates the empirical division between disks and mergers at  ⟨ K_lim ⟩  = 0.085. Bottom: the probability distribution function (PDFs) derived from the respective MC realizations. The empirical delineation clearly separate the two classes defining a small range of possible values (i.e., K_lim area). Small deviations  ⟨ k₅/k₁ ⟩  are found for disks, while higher values are found for mergers, which is consistent with our expectation.
