Left: (mid-IR based) AGN fraction αAGN as a function of the ratio LAGN/Lbol, with LAGN = 3 × 103L[OIII] and Lbol = 1.15× LIR. The nuclei of binary systems are connected with a vertical line; larger symbols refer to the sources with dominant AGN ionisation according to our BPT diagnostics. Right: [O III] and Na ID non-parametric velocity w80 as a function of the AGN fraction αAGN, defined on the basis of mid-IR diagnostics (Sect. 1). Each nucleus is identified with a distinct colour, as in Fig. 6.
