  "abstract": "Recent work has shown that the emission from X-ray binary (XRB) populations in galaxies varies with stellar mass ( M ⋆ ), star formation rate (SFR), and metallicity ( Z ). Such scaling relations are widely used to predict the XRB contributions to galaxy-integrated X-ray luminosities including studies focused on dwarf active galactic nuclei (AGN) and the X-ray radiation field during the epoch of heating in the early ( z ≥ 8) Universe. However, as galaxies approach low SFR and low Z , the relatively shallow slope of the XRB luminosity function (XLF) can yield very large stochastic variations in the total X-ray luminosity expected from the XRB population for fixed values of M ⋆ , SFR, and Z . We have created a procedure to statistically sample any XLF and model total X-ray spectra for XRB populations and their stochastic uncertainties. We demonstrate the accuracy of this procedure using data for galaxies ranging from high to low M ⋆ , SFR, and Z and generating X-ray spectral models consistent with Chandra observations. For galaxies that lie on the galactic main sequence, we can relate SFR and Z to M ⋆ using established M ⋆ –SFR and M ⋆ – Z relations. Applying these relations, we construct main-sequence XRB spectral models, which provide typical XRB spectral shapes, normalizations, and uncertainties as a function of M ⋆ .
