Upper panels: ALMA 12CO(1–0) and 12CO(2–1) line spectra extracted at the stellar position (1.7′′ and 1.2′′ annuli, respectively). The red lines show the global best-fit model as discussed in the text. Lower panels: ALMA radial intensity profiles in the 12CO(1–0) and 12CO(2–1) lines over-plotted with our best-fit model.
