Comparison between AT2017gfo data (apparent AB magnitude) in the B, g, r, i, z, Ks bands (diamonds) (Villar 2017) and the KN light curves corresponding to the brightest and the faintest KN signals obtained by selecting (BNSs) with chirp mass M_chirp = 1.186±0.005 and binary mass ratio q>0.725 from the population with α = 1.0 and Gaussian mass distribution. Dashed and solid lines correspond to the case of APR4 and BLh, respectively.
