Spectroscopic results of SDSS J001050.52−103246.6. Left and right panels present the best-fitting results to the emission lines around Hα and Hβ, respectively. In both panels, the cyan components indicate the spectrum after subtracting the host galaxy starlight; the thick red components indicate the best-fitting results; and the solid lines in the bottom region of each panel indicate residuals. In the left panel, the thin red and thin blue Gaussian components from left to right indicate the double-peaked features of narrow [N II]λ6550 Å, Hα, [N II]λ6585 Å, [S II]λ6718 Å, and [S II]λ6732 Å; the green Gaussian components indicate the extended emission components in [N II]λ6550 Å, Hα, and [N II]λ6585 Å. In the right panel, the thin red and thin blue Gaussian components from left to right indicate the double-peaked features of narrow Hβ, [O III]λ4959 Å, and [O III]λ5007 Å. In each panel, the corresponding χ²/d.o.f. related to the best-fitting results is marked in the title.
