Relation between the SFR and [Cii] (top), [Oi]₆₃ (middle), and [Oiii]₈₈ (bottom) luminosities 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 best-fit SFR calibration is presented as a solid, black line. The dispersion of data points around the SFR calibration is indicated at the top of each panel, with the number in parentheses indicating the scatter for the complete sample with >5σ detections for all three lines.
