Radial distribution of the dust properties in the CPD of PDS 70 c in the Drift and Ring models for the fiducial case. For the Ring model, the solid and dotted curves indicate Z_base = 10⁻⁶ and 10⁻⁴, respectively. The different shades of each color represent the ALMA bands in the right two panels. The dashed curve in the left upper panel is the gas surface density of the CPD, used in both Drift and Ring models. The vertical dotted lines indicate the centrifugal radius.
