Left: best-fit SED models (median and 1σ error) from photometry of two companions on the outskirts of the CRG with photometric redshifts that are similar to the spectroscopic redshift of the CRG. Right: model-subtracted, 2″ cutout of the F277W image. The subtracted emission is modeled as a 2D Sérsic profile. The image scaling is tuned to highlight the nearby companions and the arm-like tidal feature extending from the edge of the ring. The locations and aperture sizes used for possible companion galaxies are indicated by the dashed circles. The two clumps with z_phot ∼ 4 are colored red, as in the right panels, while the other clumps, colored in blue, have z_phot ∼ 1.0–1.5, and are most likely foreground sources.
