Best-fit accretion disk plus Gaussian models, overlaid on the emission line profiles of He II (left panels) and Hα (right panels). Black represents the data, blue the accretion disk model, and orange the accretion disk plus outflow model. The best-fit Hα models are overplotted in the He II profiles as dashed lines for comparison. The red wing of He II is poorly subtracted, leading to some differences with the Hα profiles, but overall the results are consistent. The model parameters can be found in Table 5.
