Adopting the model discussed in Eide et al. (2018), we find that these X-ray sources during the Epoch of Reionization (EoR) contribute less than a few percent of the unresolved X-ray background. The same sources contribute to less than $\\sim$2\\% of the measured angular power spectrum of the fluctuations of the X-ray background.
