Sketch of the best-fit model for the core of both the wing and the core components of Hα (top) and Hβ (bottom). The blue and green lines in the top right of the image correspond to the line of sight intercepting the shock. The different inclinations for the blue and green lines are due to the two local minima in the grid (see Figs. F.1 and F.2). The planet in the center and its “apparent shell” of a different color represent the size of the planet in the wing (blue) and core (green) component modeling. Left insets: Data for the wing and core (blue and green) components and the best fit (black line), along with the fitting limits (dashed red lines).
