Caption: Figure B1.

Same as Figure 1 but now also with two other radial cuts for the satellite populations. This time along with plotting all cold gas at r ≳ 10.0· R0.5 (i.e., CGM-Satellites case; dashed light blue and light red) of each satellite within a halo, we also show the mean cold gas spherical densities for R5 (r ≳ 5.0· R0.5; dashed dark blue and dark red) and R2 (r ≳ 2.0· R0.5; dashed teal and maroon). As before, the density profiles for the CGM+Satellites case are depicted with solid lines. Thus, the difference between similarly colored dashed lines is an indicator of the cold gas lying solely in the extended environments of satellites.
