Spectral energy distribution of the Circinus AGN for the three apertures drawn in Fig. 5. Also shown are four ATCA measurements at varying beam sizes (Elmouttie et al. 1998) in white. The dashed lines represent a power-law (F_ν ∝ ν^α) fit of the 300 mas nuclear aperture containing both a dust component with α = 3.5 and a free-free component with α = −0.1. We also plot the nuclear dust model by Stalevski et al. (2019) in orange.
