Extended Data Fig. 3: Constraints on joint posterior distributions and star formation histories (SFHs) with BAGPIPES.

Various SED models with different SFH assumptions (constant in purple, delayed-tau in green, and continuity in orange) are implemented using BAGPIPES and the measured model fitting photometry. In the lower left, the joint posterior distributions are shown for stellar mass (M_*), stellar metallicity (Z_*), mass-weighted stellar age (t*), star-formation rate averaged over the previous 10 million years (SFR₁₀), diffuse dust attenuation as measured in the V-band (A_V), and rest-frame equivalent width for the nebular emission lines Hβ and [OIII]λλ4959, 5007 (EW_[OIII]+Hβ). In the upper right, the derived SFHs are shown. The medians of the derived SFHs are the colored lines, while the 1σ confidence intervals are the shaded regions. This figure highlights degeneracies between some of the inferred physical parameters.
