Anaglyphs to visualize the three-dimensional structure of the large smooth patch. These are composed of: (a) cyan ITS image 5070405_9000639 paired with the red deconvolved HRI image 5070405_9000904, (b) cyan image 30034 combined with red image 30035 from SDN, and (c) cyan postimpact 5070405_9000999 overlaid with red image 5070405_9001012, both MRI images. The resultant three-dimensional perspective distinctly illustrates that the central region of the smooth patch dips lower than its surrounding sides, forming a discernible U-shape.
