[OIII] doublet SDSS spectrum of J0853+38. Wavelength in Å. A fit (green) and residuals (red) are shown in the top panel with the data (black). The three kinematic components isolated in the fit are shown in the bottom panel with different colours. The broadest component may trace an ionised outflow, but higher S/N data is needed to confirm this. Wavelength in Å. Fluxes in units of 10⁻¹⁵ erg s⁻¹ cm⁻² Å⁻¹.
