Figure 13. A close look at the upper envelope of traditional Saturn models (Mankovich et al. 2019), the same models seen in Figure 2 in the main text. The solid black curve is the ensemble median density at each radius, with the light-gray band denoting the 1σ variation. The red and blue dashed lines are best-fit polynomials of degree 2 and 4, approximating the density profile in the upper envelope as a whole. Neither is a good approximation in the small region where s R0.95 m.
