Normalized continuum flux at 346 GHz (blue lines) and CO J = 3–2 (345.795 GHz) integrated intensity (red lines) along the major axis of the disk, and respective 3σ rms values (dotted lines). The dashed black lines show a r−2 power law overlaid on the CO integrated intensity. The beam size is represented by the thick horizontal line in the top right-hand corner.
