Caption: Figure 2.
Radial profile of the 1.14 mm dust emission from the GGD27 MM1 disk, obtained by averaging the emission over elliptical rings (filled squares). The blue and dashed line show the best-fitted profile (see Section 3.1) and the beam profile, respectively. The error bars show the rms dispersion within each ring for the data. The vertical dotted line indicates Rturn, the radius where the power law changes.
