Relation between SFR–EW(CIII]) (top panel) and SFR–C/O (bottom panel). Stars symbols are Stack A color-coded depending on the parameter used for stacking, according to legend, as in Fig. 13. Top panel: the black squares are results from CIII] emitters in Maseda et al. (2017). The small dots are the C3 sample with same colors as in Fig. 10. Bottom panel: the dashed black line is the best fit for the SFR–CO relation in Eq. (9).
