Models and observational predictions for PDS 70disk. Left: comparison of the azimuthally averaged radial intensity profiles of the depro-jected images of the continuum from ALMA Band 7 observations (crosses) and the synthetic images from Fig. 4. The shaded area is the standard deviation of each elliptical bin divided by the square root of the number of beams spanning the full azimuthal angle at each radial bin. Right: predictions for several ALMA bands for the case where a_initial = [10⁻⁶–10⁻⁴] cm, assuming that all the images have the same resolution as the observations in Band 7 (Fig. 4).
