Large-field grayscale color-inverted g, r, z images centered on two galaxies (ID 1 and ID 54). The image is smoothed with a Gaussian of σ = 1.5 to highlight any possible large-scale faint merger features. We show only two galaxies here, but performed this exercise for all galaxies to detect any faint features that are otherwise not seen near to the galaxy.
