Notes. (1) IRAS name. (2) Alternative name. (3) Name of the nucleus. (4) and (5) Coordinates of the nuclei derived from the ALMA 1.4 mm continuum. If the continuum is not detected, the coordinates are measured from the NIR or optical HST (see Perna et al. 2021). (6) Infrared luminosity of the nuclei. For the interacting systems, the proportion of IR luminosity in each nucleus is based on their relative ALMA continuum fluxes (see Pereira-Santaella et al. 2021). (7) Morphology of the system. I: interacting system with nuclear separation > 1 kpc; M: advanced merger with nuclear separation < 1 kpc. (8) Nuclear separation. (9) Nuclear activity classification based on optical spectroscopy (see Perna et al. 2021). (10) Fraction of AGN contribution to L_bol derived from the 30 μm to 15 μm flux ratio (see Perna et al. 2021). (11) Combined nuclear activity classification used in this paper. Nuclei are classified as AGN either if α_AGN ≥ 0.5 or if their optical classification is Seyfert (Sy 1 or Sy 2). (12) Objects classified as compact obscured nuclei (CONs) using ratios of the equivalent widths of different polycyclic aromatic hydrocarbons (PAHs) based on the method by García-Bernete et al. (2022). ^( ⋆ ): For 14348−1447, there is evidence that the AGN is located in the SW nucleus based on high-angular resolution mid-IR imaging (Alonso-Herrero et al. 2016). ^{( ⋆ ⋆)}: Even though this target (Arp 220) is classified as a merger (d_nuclei = 0.37 kpc), we report the position of the two nuclei that have been identified thanks to the low redshift of this source. For consistency, we treat this target as a single nucleus in the rest of the paper.
