Observed 0.5–2 keV luminosity in the 0.5–2 (top panel), 2–10 (middle panel), and 8–24 (bottom panel) keV bands vs. SFR. The luminosities are corrected for Galactic absorption. The black solid line represents the relation between the X-ray luminosity of the XRB emission and SFR found by Mineo et al. (2012). Here we convert the 0.5–8 keV luminosities to the 0.5–2, 2–10, and 8–24 keV ones by multiplying 0.29, 0.85, and 0.61, respectively (based on a power law with Γ = 1.1 and E_cut = 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.
