Gallery of azimuthally averaged radial intensity profiles on a log-linear scale for each source. The deprojected profile from robust 2.0 CLEAN images (black solid line) and the frank model (red solid line) are shown, with uncertainties as described in Figure 2. Dashed–dotted gold vertical lines mark R₉₀ for each disk. For Sz 73 and Sz 130, dashed–dotted teal vertical lines mark R₉₀ computed including their faint outer rings, indicated by teal arrows. The purple shaded region marks intensity levels below 3σ_rms, where σ_rms is the rms noise of the CLEAN image scaled by the square root of the number of beams within each radial annulus to account for the radial dependence of the azimuthal average.
