Representation of two of our fiducial multi-messenger synthetic populations in a geocentric universe. Compact binaries that are detected by ETΔ are represented by yellow (NSNS – left semicircle) and orange (BHNS – right semicircle) dots. The distance of each dot from the Earth (blue circle) is proportional to the redshift of the corresponding compact binary. If the simulated merger produces a relativistic jet whose prompt or afterglow emission is detectable, according to the limits reported in Table 2, a cyan jet is plotted centered on the dot, with its axis inclined by the actual viewing angle with respect to the line of sight to the Earth. If a KN is also produced and if it is detectable, then a red butterfly shape is also plotted. The total number of binaries is representative of 5 years of ET operation.
