Best-fit profiles and residuals for Sim 1 at 11 Gyr for two-component King models (green) and for two-component models (black). Upper panels: density profile for light component (left) and for heavy component (right). Lower panels: density residuals for light component (left) and for heavy component (right). Vertical lines represent the half-mass radius of the component under consideration in the simulated state and in the models.
