Dust temperature, density, maximum size, and density distribution power-law index posterior distributions for our fiducial ‘Ricci (compact)’ composition. The blue solid lines and shaded regions display the median and 1σ uncertainty of each parameter. For comparison, the dotted lines show the results of the low resolution fit. The hatched areas mark the disc region within the synthesised beam minor axis ($0_{\cdot }^{\mathrm{\prime }\mathrm{\prime }}058$) and, in the outer disc, the region where our fit does not provide robust results due to the low S/N of the data. The grey dashed line displays our ALMA Band 6 surface brightness radial profile (at a resolution of $0_{\cdot }^{\mathrm{\prime }\mathrm{\prime }}058$), the bright ring position is indicated and labelled as in the previous plots. The black and grey horizontal arrows mark the regions where the S/N of VLA Ka band surface brightness radial profile is >5 and 3.
