Example of SED fitting results for a galaxy with oxygen abundance measurements (1210_5173 at z ≈ 7.99). The NIRSpec prism spectrum (black) and the best-fit model (red) are depicted with their respective 1σ uncertainties. The vertical lines indicate the positions of key optical emission lines we used to estimate the oxygen abundance: Hγ and Hβ (orange), [O II}] λ3728 (purple), [O III] λ4363 (blue), and [O III] λ5007 (green). The vertical dashed gray lines indicate the positions of the remaining emission lines. The olive lines indicate the continuum emission levels.
