Fig. 10


Upper panel: neon, sulphur and silicon diagnostic diagram from Dale et al. (2006). Dotted, solid and dashed lines divide the plane according to Dale et al. (2006) classes: AGN and LINERs (classes I and II), HII nuclei and LINERS (class III) and HII regions (class IV). The different symbols in the diagrams represent the different MIR spectral classes of ETG described in Sect. 4 and reported in Table 5: Class-1 = filled circles; Class-2 = crosses; Class-3 = triangles; Class-4 = diamonds. See text for details. Bottom panel: Dale et al. (2006) diagnostic diagram, i.e. Log ([Ne iii]15.5 μm/[Ne ii]12.8 μm) vs. the Log([S iii]33.48 μm/[Si ii]34.82 μm) plane. Models for starburst galaxies (SB: Dopita et al. 2006), for AGNs (Groves et al. 2004a,b), and for fast shocks (Allen et al. 2008) are shown.
