(a) Variation of mean values of 𝑆_𝑛/𝑆_𝐿 conditional on normalised curvature 𝜅_𝑚×𝛿_th for the isosurface at 𝑐=0.8. (b) Variation of the correlation coefficients between 𝑆_𝑛 and 𝜅_𝑚 on the isosurfaces at c = 0.1 to 0.9 for all cases. (c) Variation of mean values of (𝑆_𝑟+𝑆_𝑛)/𝑆_𝐿 conditional on normalised curvature 𝜅_𝑚×𝛿_th for the isosurface at 𝑐=0.8. (d) Variation of the correlation coefficients between (𝑆_𝑟+𝑆_𝑛) and 𝜅_𝑚 on the isosurfaces at c = 0.1 to 0.9 for all cases.
