Correction of the brightest pixel of J0313-1806 using WICKED. Top: Brightest spaxel spectrum of J0313-1806, shown as a solid red line, fitted using a combination of an aperture and annular integrated spectra (black and yellow lines) templates, a power-law, and a second-degree polynomial, and shown in blue. Red vertical lines indicate masked regions of known emission lines excluded from the fit. The gray dots display the residuals. Middle: Wiggle spectrum is shown in gray and the best-fit wiggle model in red. The green X’s are the peaks and valleys of the wiggle spectrum used to divide the wiggle spectrum to constrain its model shown in red (see Dumont et al. (2025) for details). Bottom: Wiggle-corrected spectrum in red and the residuals in gray.
