Angle dependency of the joint GW+γ-ray detections for three redshift bins, considering ET+Fermi-GBM. The bands are obtained with random realizations extracted from the MCMC posterior samples. For each redshift bin, the y-axis gives the number of joint detections normalized to 5 × 10⁴ BNS injections with viewing angle 0 ° < θ_v < 15°. We assume that all BNS produce a jet (f_j = 1).
