L_X–SFR–metallicity relation of the GPs. Green open circles with error bars represent the GPs in this study. The solid line denotes the best-fit L_X–SFR–metallicity relation from Brorby et al. (2016), with dashed lines indicating a dispersion of σ = 0.34 dex. Red circles represent SFGs from Douna et al. (2015), and magenta squares represent LBAs from Brorby et al. (2016). Orange open circles indicate seven detections from Chandra observations, while orange triangles denote the four upper limits for low-redshift SFGs (Senchyna et al. 2020).
