Comparison of spatially resolved emission-line parameters across the GMOS FoV before (upper panels) and after (lower panels) applying the QSO-host galaxy deblending for each QSO. From left to right we present the [O iii] surface brightness distribution (Σ_{[O iii]}), the median line velocity (v_median), the line width covering 80 per cent of the line flux (W₈₀), the line asymmetry parameter (A), and the kurtosis parameter (K).
