Fig. 7
Effect of extra heating in the H i region. The electron temperature (top panel) and the fraction of C ii and C ii* to total carbon (middle panel) are shown as a function of radius to the ionizing stars. The predicted line strength is shown in the bottom panel. The models assume unity for both the covering fraction of the H ii region and the fraction of the emission subtended by the COS aperture (see Sect. 4.2).
