Comparison of ALMA band 7 data (left panel) with the best-fit composite “disk + disk + Gaussian” model (2ndpanel). The 3rdpanel shows the imaged residuals. We draw red and blue contours at 5 times the image rms of 0.11 mJy. Units of all intensity scales are in mJy/beam. The central two panels include ellipses representing the 2 fitted disk components to guide the eye. These are drawn at the radial location corresponding to the inner and outer disk radius for disk #1 (thick line) and disk #2 (thin line), as summarized in Table 2. The right panel (top) shows the real part of the visibilities as function of the deprojected baseline for the data (black dots) and the model (red line). The bottom panel shows the residuals. The visibilities are binned in sets of 200.
