Line luminosity ratio of [O III] and [C II] vs. SFR for each component of A1689-zD1 compared to other high-z detections (Inoue et al. 2016; Laporte et al. 2017, 2019; Carniani et al. 2017; Hashimoto et al. 2018, 2019; Tamura et al. 2019; Harikane et al. 2020; Witstok et al. 2022; Algera et al. 2024; Bakx et al. 2024). The diamonds represent the individual components color-coded according to their name, and the star formation is the one derived from the aperture measurements, as given in Tables 6 and 5. The orange and gray region and line indicate the range of the line ratio for local low-metallicity dwarf galaxies and starburst galaxies from De Looze et al. (2014).
