Composite red-green-blue image of the eastern region of the field showing a compact overdensity of seven galaxies (dashed boxes) identified within a radius of 17″ centered at (RA, Dec) = (159.2840°, −58.5948°). The image combines F200W, F335M, and F444W filters. The bright vertical feature corresponds to a diffraction spike from a saturated star. The bright galaxy along a diffraction spike corresponds to Galaxy 4 (see Sect. 5) and is not considered in the analysis. The figure is oriented in detector-native X/Y coordinates; north is rotated 102° counterclockwise from vertical.
