Fig. 1: Gravity and topography maps of giant tapered impact basins.
From: Southward impact excavated magma ocean at the lunar South Pole–Aitken basin
a–f, Maps of the SPA basin in Bouguer gravity (a), gravity gradients (b) and topography (c) in comparison with topographic maps of the Hellas basin on Mars (d), the Crisium basin on the Moon (e) and the Sputnik basin on Pluto (f). All figures are in a basin-centred polar projection with basins oriented with the inferred downrange direction to the bottom. The rim picks are traced in black, with the mean and 1σ fits for a tapered ellipse in white and grey. The tracing in a and b are the same, based on a combination of the two datasets.
