Radial intensity profiles of the dust emission of the disk around TW Hya at 0.87 (top-left), 1.3 (top-right), 2.1 (bottom-left), and 3.1 mm (bottom-right) convolved to a circular 0.″05 beam. The colored shaded regions indicate the error bars at each radius (including the flux calibration error). The solid and dashed lines show the model intensity profile with maximum posterior probability for a_max > 200 μm, using a varying p or fixing it top = 3.5, respectively. The Gaussian inset in the top-left panel displays the beam shape (the same at the four wavelengths). Our model is able to accurately reproduce the observed profiles at all radii except r < 20 au.
