Comparison of normalized azimuthal profiles (red curves) for five different radial integration distances Δr based on run 5 at 150 kyr (corresponding to the synthetic ALMA observation shown in Fig. 5). The dashed red ellipse in the center of each plot shows the underlying assumed inner disk, whose properties were chosen according to those of the approximate ideal inner disk. The blue curves show ideal azimuthal profiles. Each red curve corresponds to the obtained normalized azimuthal profile of each plot, assuming the Δr value above the plot.
