X-ray luminosity distributions of the present-day population of LMXBs, including UCXBs, with neutron star accretors in the Galactic Bulge. The star formation history width is σ = 0.5 Gyr (solid line) and σ = 2.5 Gyr (dashed line). These distributions include hydrogen-rich as well as hydrogen-poor LMXBs, and both persistent sources and transient sources in outburst. The dotted line shows the X-ray luminosity function parametrized by Gilfanov (2004, sample “All” in Table 3) using the best-fitting normalization of K₁ = 440.4, and further adjusted for the bin width of our histograms to allow for direct comparison.
