Thickness change at the equator after ejecta accumulation on Didymos (Modification I), i.e., Δt_e = (χ − 1)(a₀ + b₀)/2. The plot shows four different pre-impact shapes. The blue line shows the case when a₀ = 413 m, b₀ = 395.5 m, and c₀ = 298 m. The yellow line illustrates the case when a₀ = 393 m, b₀ = 375.5 m, and c₀ = 318 m. The green line shows the case when a₀ = 433 m, b₀ = 415.5 m, and c₀ = 318 m. Finally, the red line shows the case when a₀ = 413 m, b₀ = 395.5 m, and c₀ = 278 m.
