Resolved thickness in the inner disk half and flat outer disk in DoAr 25 and HD 142666. For both disks, “Flat” models show too strong of a gap in the inner region (third panels), indicating that the disks must be thicker. On the other hand, “Moderate” and “Thick” models do not reproduce the gap and ring in DoAr 25, and the outer disk profile in both disks (last panels), highlighting the presence of a flat outer disk. The beam size and a 25 au scale are indicated in the bottom left corner of the first panels.
