Distribution of the total expected X-ray luminosity per SFR due to the stochastic sampling of the HMXB XLF from L21, as a function of the metallicity of each galaxy in our sample. Orange-, pink-, and goldenrod-shaded regions indicate the 90%, the 99%, and the 99.9% CI, respectively, of the expected L_X/SFR distribution of each BB. Filled blue squares and down-arrows indicate the BB sample of this work. We also plot with filled green squares and down-arrows the GP sample from Svoboda et al. (2019). For comparison, we overplot with a red dot-dashed line the scaling relation from Brorby et al. (2016), with a grey dashed line the relation from Fornasini et al. (2020), and with a black dashed line the relation from Lehmer et al. (2021).
