Best-fit Prospector spectral energy distribution for COLA1 (gray line) and all models allowed within 1σ (gray shaded regions). The errors of the observed photometry are increased by a factor three for visual clarity. The code fails to reproduce the steep blue slope seen in the observed F115W-F150W color. The predicted F356W flux is also lower than observed, causing a slight underestimate the EW of the optical lines [O III] +Hβ.
