Distributions of the initial conditions to set up our synthetic population, described in Section 3.2. Note that panel d) shows both the distribution of the actual 3D FUV field experienced in the cluster as well as the 2D projection and the X-ray luminosity distribution is shown in panel c). In panel f) we show the two sets of $\overline{{\alpha }_{r\varphi }}$ and $\overline{{\alpha }_{\varphi z}}$ that result from the two accretion timescales adopted (see Figure 3).
