Palomar TripleSpec spectrum (order 3). Wavelengths are in the observer’s frame. Relevant lines are labeled at the top of the panel. The vertical dashed lines indicate the wavelengths of the lines corresponding to the systemic redshift z_h = 1.0685. The best fit is the red line. Each component of the model is shown separately, added to the continuum power law, for clarity. The emission components are shown in cyan and blue for He I and Pa γ, respectively. The absorption component is plotted in green. Model residuals are shown in the bottom panel.
