Vertical surface profiles for HCN (top row) and H₂CO (bottom row). The green vertical line marks the edge of the dust continuum as reported in Law et al. (2020a). The solid and dashed lines in each panel mark the rings and gaps, respectively, found in the emission maps of each molecule from Law et al. (2020a). In the profiles, the solid line marks the mean value and the grey shaded area the dispersion of the retrieved data points in each radial bin.
