Emitting radii of the CO lines (colors) compared to the dust continuum radius determined from VLTI-Gravity (black circle; GRAVITY Collaboration 2021, values corrected for a different adopted distance). S CrA N is presented in the top panel and S CrA S in the bottom panel. For both stars, the broad component is coming from the inner, dust-free region, while the narrow component is coming from larger disk radii.
