Comparison of the values of correctly identified disks (Idisk) and mergers (Imerger) along with their associated Ktot (optimal) values when using the “unweighted” and “weighted” methods at low- and at high-z.

Notes. All these values are computed in the cases when, as “true disks”, we assume: [case I] isolated and paired disks; [case II] only isolated disks. In both the cases ongoing and post-coalescence mergers are considered “true mergers”. Column (1): method used: S08 and B12 stands for “unweighted” and “weighted” methods. “obs” and “sim” stand for observed and simulated samples. Column (2): fraction of well-classified disks over total number of disks as defined in Eq. (6). when isolated and paired disks are considered “true disks”. The corresponding percentage is in brackets. Column (3): fraction of well-classified mergers over total number of mergers as defined in Eq. (6). when isolated and paired disks are considered “true disks”. The corresponding percentage is in brackets. Column (4): value of the total (optimal) kinematic asymmetry derived when isolated and paired disks are considered “true disks”. Columns (5–7): the same values as in Cols. (2–4) when only isolated disks are considered “true disks”.
