C III] doublet EW versus SED-derived parameters (median and ±1σ uncertainties) with the MUSE sample shown by pink points, galaxies from Stark et al. (2014) shown by blue points, and galaxies from Du et al. (2017) shown by yellow squares. HDFS galaxies with no constraints on β are shown with arrows. Stark et al. (2014) SFRs come from their quoted sSFR values and their quoted M_⋆ values. In the case of stellar mass (SFR), EWs in excess of 5 Å are only found in galaxies with M_⋆ ≲ 10^9.5M_⊙ (SFR ≲ 10 M_⊙ yr^-1).
