Medium (left) and high (right) resolution spectra of ID 73488, zoomed around Hα with the fit overlaid using a narrow (Gaussian) component (dashed blue line) and a double power-law profile (dashed purple line) to describe the broad component. The total fit is shown with the dashed red line. The double power-law profile fails to properly fit the broad component, as is highlighted by the strong residuals, which are shown in the bottom panels.
