Lens-system configurations of the close (upper panel) and wide (lower panel) 2L1S solutions of KMT-2022-BLG-0475. In each panel, the red cuspy figures are caustics and the line with an arrow represents the source trajectory. The whole view of the lens system is shown in the inset, in which the small filled dots indicate the positions of the lens components and the solid circle represents the Einstein ring. The gray curves surrounding the caustic represent equi-magnification contours.
