Stellar mass, log₁₀(M_⋆); UV magnitude, M₁₅₀₀; β slope; E(B–V); and log₁₀(sSFR) for 436 sources in our sample, derived using Prospector. The ionizing photon production efficiency, log₁₀ξ_ion, was calculated for all sources with detectable Hα or Hβ using the relations proposed by Leitherer & Heckman 1995; Schaerer et al. 2016. The figure shows the median values along with their standard deviations (16th and 84th percentiles) for each distribution.
