Notes. In addition to inclination and position angle, the amount (Δu) and angle (αu) of offset of the fitted ellipse center from the stellar position is given. The height of the disk at the radius of the fit is given only taking the offset component into account that is in the direction of the disk semi-minor axis. For the HD 97048 and SZ Cha systems multiple rings were fit independent of each other. The fit column indicates whether the fit was performed based on the SPHERE data alone (SPHERE), using the SPHERE data but with inclination constrained to within 2° of the ALMA value (SHERE/con), or if its based on ALMA (literature) data (ALMA).
