Distribution of obtained data points corresponding to different guessed inner disk shapes and sizes (black dots) in the A_mask-Î_rim plane based on a synthetic ALMA observation of run 5 at 150 kyr and 850 μm. The blue curve marks the position of most suitable inner disk guesses. A red star highlights the position corresponding to an inner disk of approximately the shape and size of the (actual) inner disk as seen in the ideal flux map.
