Scheme showing the different dust geometries and compositions of the various torus models used in this work. See Appendix A for further details on the individual model parameters. Note that the clumpy disc H17D models are not represented in this figure. However, the latter models consist of clumpy disc component of the clumpy disc+wind H17 models. (a) Smooth F06 torus models, (b) Clumpy N08 torus models, (c) Clumpy H10 torus models, (d) Two-phase S16 torus models, (e) Clumpy disk+wind H17 models.
