- Aratus has a flat bottom with tapering walls. As measured by [/LTVT LTVT] the shadows in both the Lunar Orbiter and Apollo images indicate the floor is 1940 m below the east wall. The Elachi depth value, though nominally the most accurate, is clearly incorrect, at least if measured from the east wall. - JimMosher JimMosher
