Distribution of the generated 106 720 AGN XUV fluxes with redshift. The shaded areas show the percentage of total flux enclosed in different ranges of z: 0 ≤ z ≤ 0.0005 (red), 0.0005 ≤ z ≤ 0.0010 (yellow), 0.0010 ≤ z ≤ 0.0015 (green), and z ≥ 0.0015 (blue). 99.7% of total flux reaches the MW from distances where z ≤ 0.0015 and the majority of the AGNs, at large distances, account for only 0.3% of total flux.
