a: [CII]158 μm line luminosity as a function of the total IR luminosity. Blue squares represent detections in AGN, red stars indicate SFGs, and green triangles LMGs. The solid red line represents the linear relation calculated for SFGs, the blue dotted line shows the relation for AGN, and the green dashed line the one for LMGs. b: [NeII]12.8 μm line luminosity as a function of the total IR luminosity. c: [NeIII]15.6 μm line luminosity as a function of the total IR luminosity. In b and c, we use the same notations as in a.
