Fit of Paα using the 0.8″ × 1.4″ EMIR (top) and 1.2″ × 4.0″ X-shooter (bottom) rest frame spectra. Left panels: data (black), fit (red) and residuals (blue), shifted on the vertical axis for visualisation. The small excess of flux on the blue wing of Paα may be H₂ 2-1S(7) λ1.8523. Right: Individual components of the fit of Paα, where the values of FWHM and ΔV in km s⁻¹ (velocity shift relative to the narrow or systemic component, in red) refer to the broadest (blue) kinematic component. It is due to a prominent ionised outflow. The spectra in these and all other figures have been normalised by the peak flux of Paα.
