Relation between the dispersion from the SFR calibrations for [Cii] (top), [Oi]₆₃ (middle), [Oiii]₈₈ (bottom) as a function of oxygen abundance, 12 +log  (O/H), on global galaxy scales. Galaxies are color-coded according to metallicity with increasing oxygen abundances ranging from black then blue, green and yellow to red colors. The Spearman’s rank correlation coefficients are indicated in the top right corner. In parentheses, we show the dispersion for the complete galaxy sample, i.e., global galaxies that have >5σ detections for all three lines [Cii], [Oi]₆₃, and [Oiii]₈₈.
