Comparison of the observed 9.7 and 18 μm silicate strengths of the sample (dots, color-coded as in Figs. 1 and 2) with those covered by three different sets of torus models (green dots). Top panel: clumpy torus models (Nenkova et al. 2008a,b). Bottom panel: smooth torus models (Efstathiou & Rowan-Robinson 1995; Efstathiou et al. 2022). Martínez-Paredes et al. (2020; their Fig. 6) show a similar plot that uses the additional clumpy and smooth torus models available in the literature.
