Line profiles showing the nuclear spectra of J1356N (top panels) and the Teacup (bottom panels), extracted in a circular aperture of 0.8″ diameter and smoothed using a 3 pixel boxcar. The corresponding fits are shown as solid green lines. Solid blue and dot-dashed red Gaussians are the broad- and narrow- line components, respectively, and the orange dashed line is the continuum. The Gaussians have been vertically shifted for displaying purposes. The insets at the bottom of each panel are the residuals. The gray dotted vertical lines mark the expected position of the line peaks according to the redshift of the QSO2s.
