The 0.5–2 keV luminosity of the unabsorbed X-ray component vs. SFR. The luminosities are corrected for Galactic absorption. The black solid line represents the relation between the X-ray luminosity of the XRB component and SFR found by Mineo et al. (2012). We convert the 0.5–8 keV luminosities to the 0.5–2 keV ones by multiplying by 0.29 (based on a power law with Γ = 1.1 and Ecut = 10 keV). The gray shaded area shows the 1σ dispersion. Symbols and colors are the same as in Figure 3. The small symbols mark the starburst-dominant or 8–24 keV nondetected sources.
