On-sky 2D view and 3D reconstruction of a potential galaxy companion for COSMOS2020 (C20) object #1006523 found during our MC process (MC iteration #87). The central galaxy (C20#1006523) is marked in gold with our 150 kpc search radius centered on that galaxy shown in green. The companion galaxy that meets both the projected separation and LoS velocity difference criteria is denoted in blue. Other nearby galaxies are shown in gray. While multiple galaxies fall within the projected separation criteria for this galaxy, the 3D LoS velocity difference cut helps isolate the single companion from other projected companions.
