... We revised topographical data obtained for the region to construct a generalized structure of the SPA basin as ringed formation. ... Because of our previous analysis of the ring structure [5, 6] we assumed the projection center o o coordinates as 180 W and 40 S. The hypsografic map shown in Fig. 1 demonstrates a hemisphere of the Moon which contains the SPA basin structure and its environs. ... Then we find the o o basin outermost ring center at roughly 180 and 40 S. Inner structure of the SPA basin...
