Caption: Figure 2.
Sky distribution of off-nuclear extragalactic transients without premerger detections. Blue circles indicate sources with photometric redshifts or no host match, and red circles indicate sources with spectroscopic redshifts. Red stars highlight the four candidates with estimated luminosity distances below 228 Mpc. The upper panels show enlarged views of the regions outlined by dashed lines in the lower panel.
