Combined detection rate of BHNS mergers in our simulated population observed through their GW emission and their associated sGRB afterglow emission. The radio emission is observed with SKA1-Mid at nominal frequency and sensitivity. The GW emission is observed with either an aLIGO detector network (blue and green circles) or an ET detector network (orange and red circles). Either a soft NS EOS (R_NS = 11.5 km) or a hard NS EOS (R_NS = 13.0 km) is assumed. The detection rate is shown as a function of the BH spin (χ_BH). The dashed black lines are not computed but connect the points to guide the eye.
