Schematic of the dust within the RT models that best reproduce the observed dust temperatures. The basis of the model comes from Stalevski et al. (2019), and a rough parameter range is given in Paper I. Here we have added a cluster of dust clouds above the disk and behind the hyperbolic cone, at a position that in projection corresponds to the central aperture. These clouds could represent, for example, a puffed-up sublimation zone, freshly launched winds, or a smoother boundary for the hyperbolic cone. The spatial resolution of these observations is not sufficient to distinguish between these scenarios.
