Comparison of ALMA band 6 data (left panel) with the best-fit composite model (second panel). Third panel: imaged residual visibilities. This panel also includes ellipses representing the fitted disk and the central components in yellow thick lines, the outer ring with a yellow thin line, andthe Gaussian component with a dark solid line. Units of all intensity scales are in mJy beam⁻¹. Top right panel: real part of the visibilities as function of the deprojected baseline for the data (black dots) and model (red line). Bottom panel: residuals. The visibilities are binned in sets of 200.
