Comparison of the cavity sizes as measured in the millimeter and in scattered light for a sample of 22 transition disks. The cyan points correspond to the two systems modeled in this paper, while the yellow star symbols refer to HD 142527 that has a stellar companion in the cavity, and PDS 70 where a planet has been detected. The upper limits, indicated with arrows, refer to systems for which scattered light cavities could not be measured down to the coronagraphic radius. Horizontal bars correspond to one tenth of the millimeter beam, while vertical bars represent the interval between the cavity radius and the peak in scattered light (Table 3). The red region shows the ratio for which the planet massinferred with the prescription of de Juan Ovelar et al. (2013) is larger than 13 Jupiter masses. The three breaks correspond to their models with planets at radii of 20, 40 and 60 au, respectively.
