Synthetic intensity maps for the planet and CPD for sim 1 at 30 µm seen at 50° inclination, to mimic PDS 70c. Those maps assume a spatial resolution far superior to ALMA, but serve the purpose to illustrate the intensity contributions to the spectral flux at this wavelength. On the left we show a intuitive heat map, on the right with a more contrasted colour map. On the right, one can distinguish several regions according to their emission intensity I : Emission from the innermost planet, originating from olivine, I ≈ 1, the CPD with the water ice line I ≈ 0.1–0.6, also marked with the white arrows, the outer edge of the CPD I ≈ 0.03, various disc structures including spiral arms at I ≈ 0.01. The arrow marks the water ice sublimation line, which through its associated drop in opacity reveals some inner parts of the envelope.
