Peak positions for the radial profiles for SPHERE (first and second from the top) and ALMA (third from the top) and the difference between the two (bottom, in log-scale), as a function of the total gas mass and for different peak optical depths (legend in the middle panel), for family F1. The second panel from the top shows a zoomed-in version of the topmost panel. For the top three panels, the horizontal dashed lines show a_d = 75 au.
