Example of the SED fitting results for a galaxy with a UV-bump detection (1210_13510 at z ≈ 5.12). Left panel: NIRSpec prism spectrum (blue) and best-fit posterior model (orange; top panel). The shaded regions represent the respective 1σ uncertainties. The vertical gray and red lines indicate the positions of potential emission lines and the UV bump absorption feature, respectively. The residuals of the best-fit model relative to the observed spectrum (Δf_λ) are reported in the bottom panel, along with the 1σ uncertainties. Right panel: Best-fit dust attenuation curve with 1σ uncertainties derived from a bootstrap method that generated 5000 attenuation curves by randomly sampling the c₁ − c₄ parameters (Eq. 1) from the posterior distribution. For comparison, the Calzetti, MW, and SMC empirical curves are shown as solid, dashed, and dotted black lines, respectively.
