Orbital period distributions of the present-day population of persistent hydrogen-rich LMXBs with neutron star accretors in the Galactic Bulge (black lines), as well as a snapshot in time of the transient population in outburst (gray lines). The star formation history width is σ = 0.5 Gyr (solid lines) and σ = 2.5 Gyr (dashed lines). Unlike the previous histograms, here the vertical scale is linear.
