SPHERE/IRDIS disk images in total intensity after the process of RDI. All panels are displayed in linear color scales. Due to different disk surface brightnesses, we linearly scaled some disk brightnesses to improve the visibility of the substructure. The star is located in the center of each image. The central gray region shows the position of the coronagraph mask with a diameter of 196 mas (16 pixels). The adopted FoV is 0.735″ in radius. For consistency, we did not increase our FoV for disks extending outside of the FoV. We note that RDI does not have a FoV limit.
