Zooms of the Hβ (top panel) and [O iii]λ5007 Å (bottom panel) emission lines (black, solid line), with the ¹²CO(2-1) emission (red, dashed line), and H i outflow absorption (blue, dotted line) overlaid. For comparison, all fluxes are normalized and the H i absorption is inverted. The horizontal dashed line shows the FWHM of ¹²CO(2-1) emission. The vertical dashed line marks the . The shaded areas mark the emission of the optical lines beyond ± 400 km s^-1, above the continuum (yellow) and 3σ (green) levels. (Color version available in electronic format.)
