Parametrisation of the Hα region of the SUPER AGN X_N_160_22. The red curve shows the best fit to the data. Green Gaussian lines refer to the narrow and broad components used to reproduce the line profile of Hα, [NII], and [SII]. The gold Gaussian component indicates the broad component of Hα associated with BLR emission. The lower panel shows the fit residuals. The x- and y-axes show the rest-frame wavelength and flux (not corrected for extinction), according to the redshift of the target, respectively.
