Central 0.4″ × 0.4″ region showing the ALMA 854 μm emission. Top panels: observed (left panel) and point-source subtracted (right panel) images from the extended configuration data set. Lower panels: same as the upper panels, but for the merged configuration. The dashed blue ellipse marks the approximate extent of the torus. In all the panels, the first contour is at 3 × rms. The gray ellipses represent the corresponding observation beams.
