Azimuthally averaged radial intensity profile of the inner 30 au of the disk of TW Hya at 0.87 mm (top-left), 1.3 (top-middle), 2.1 (bottom-left), and 3.1 mm (bottom-middle), obtained from the higher resolution images shown in the insets of Fig. 1. In order to minimize the effects of the elongated beam at 2.1 mm, the radial profile at this wavelength was obtained by averaging the emission only within two 90° slices in PA across the minor axis of the beam. The inset in this panel shows the geometric mean of the full beam size, so the resolution of the profile will be slightly better than the one displayed by the inset. The lines and colored regions indicate thesame as in Fig. 2. The right panel displays the same four profiles in units of brightness temperature.
