F_ν, AB magnitude, and νF_ν versus time for the GRB afterglow light curves associated with O5-detectable sources in our population. In the top panel we assume a jet core half-opening angle θ_j = 3.4°: in the lower panel we assume θ_j = 15°. Solid and dashed contours contain 50% and 90% of the peaks, respectively. Red, green and blue colors indicate the radio (1.4 × 10⁹ Hz), optical (4.8 × 10¹⁴ Hz), X-ray (2.4 × 10¹⁷ Hz) bands, respectively. The colored circles are the observed data of GRB170817A (Makhathini et al. 2021) at the median distance of the GW triggers. The gray lines in the background are 300 randomly sampled light curves in the respective bands.
