Top: weighted asymmetry measures of the velocity and velocity dispersion fields derived from the Monte Carlo realizations for the four objects. For each source, 150 MC simulations are run but only the  ± 3σ results are shown. The solid red line indicates the empirical division between disks and post-coalescence mergers at  ⟨ K_tot ⟩  = 0.146. Bottom: the probability distribution function (PDFs) as derived from MC realizations. The empirical delineation K_lim = 0.146 clearly distinguishes the two classes along with a large range of other values (i.e., dashed K_lim area).
