Fig. 6

Best-fits of the spectrum of the extended emission using a collisionally ionized plasma model (left panel) and a photoionized plasma model (right panel). In each panel, we show the total best-fit model (solid line), the spectral components separately (dotted lines), and the residuals in terms of χ2. The spectral components are labeled as in Table 4.
