Line-to-continuum ratios for the [FeII] (blue stars), Brγ (green dots), and H₂ (red squares) emission lines. Displayed points each have an S/N > 3. The seeing (and nuclear aperture) is indicated with the black bar. The off-nuclear apertures are delimited by the vertical dashed lines at (+/−)375 pc and (+/−)125 pc. The minimum and maximum 1σ error for each emission line are displayed in the upper right corner.
