We parameterize the XLF normalization (green short-dashed) and slope (orange long-dashed) as functions of metallicity by fitting the observed ﹩{L}_{\mathrm{HX}}﹩/SFR of the full sample of six LBAs (gray points), the average BCD population (blue square) and the local star-forming galaxy relation (black dotted line) at solar metallicity (﹩12+\mathrm{log}[{\rm{O}}/{\rm{H}}]=8.69﹩). The top panel (a) is similar to Figures 2 and 8, but has been expanded to include the extremely metal-poor dwarf galaxies, shown as blue lines (dashed–dotted for Brorby et al. 2014 and dotted for Douna et al. 2015). We also included our best-fit XLF as a black solid line, spanning the metallicity range for Haro 11 and VV 114. The middle (b) and bottom (c) panels show the parameterizations of the normalization (ξ) and bright-end slope (﹩{\gamma }_{2}﹩), respectively. Each parameter is fit while holding the other fixed at the standard XLF value. The black stars show the standard XLF values at solar metallicity.
