Deprojected normalised optical depth of the disk at mm wavelengths (orange line extracted from data published in Pawellek et al. 2021), in the optical with STIS (green line Stark et al. 2014, assuming a 2% uncertainty), and in the near-infrared with IRDIS (blue line). The top panel shows the data (plain lines) with the 1σ uncertainty (shade) and the double-power law fit (dotted line limited to the range of separation where the fit was performed). The bottom panel is a zoom in the region where the optical depth peaks, highlighting with vertical dotted line the location of the maxima.
