Shapes of minimal energy fusion pores for symmetric and asymmetric bilayers with R_b = 3 nm. Plots on the left show bilayer midplane contours and plots on the right show the radius of meridian curvature, R(s), of the bilayer midplane as a function of distance from the pore axis. a Bilayer midplanes for the minima from Fig. 6c show the shape of minimal energy fusion pores with the monolayer spontaneous curvatures summing to 0. a C_m-i-0 = C_m-o-0 = 0, b C_m-i-0 = 0.05 nm⁻¹ and C_m-o-0 = −0.05 nm⁻¹, c C_m-i-0 = −0.05 nm⁻¹ and C_m-o-0 = 0.05 nm⁻¹. b Bilayer midplanes for the minima from Fig. 6d show the shape of minimal energy fusion pores with the monolayer spontaneous curvatures summing to −0.2 nm⁻¹. a C_m-i-0 = C_m-o-0 = −0.1 nm⁻¹, b C_m-i-0 = −0.05 nm⁻¹ and C_m-o-0 = −0.15 nm⁻¹, c C_m-i-0 = −0.15 nm⁻¹ and C_m-o-0 = −0.05 nm⁻¹
