Radial profiles of the density in the considered loop model for density contrast χ = 1/9 and different values of the cord-shell radii ratio. The solid, long dashed, dashed, dotted, and dot-dashed curves correspond to the values of a/R = 1, 0.8, 0.5, 0.1, and 0.01, respectively. The vertical axis denotes the value 1 /χ = ρ_i/ρ_e. The radial distance is normalized to the cord radius a.
