Light curves of the four candidates located within ±5σ of the mean estimated distance. The luminosity distances of both the candidates and the AT 2017gfo-like kilonova are determined from their spectroscopic or photometric redshifts. The adopted distance for each object is indicated in the corresponding panel title, with uncertainties shown for distances derived from spectroscopic (upper panels) or photometric redshifts (lower panels). The template, science, and difference-image cutouts corresponding to the first detection are shown in the upper-right corner of each panel. The candidate position is marked by a red dashed circle in each cutout, while the corresponding photometric measurement in the light curve is marked by a red open square.
