Section of the nuclear spectrum of PKS B1934-63 showing the Fe II 1.257 μm(top panel) and the Paβ (bottom panel) emission lines (black solid line). The best-fit model is shown with the red solid line. The residuals of the fit are normalized and plotted below the spectrum (black dot-dashed line). The vertical dashed lines mark the restframe wavelength of the emission line. For the Paβ, the model includes two narrow components (green dotted line) and a broad component (blue dashed line).
