Radial flux profiles of the stacked CG galaxies for all the redshift and magnitude bins in this work. The mean redshift of each subset is shown in the title of the panel, and the mean magnitude of the bins in each redshift is shown in the labels. The brightest bin is shown in red dashed line, the intermediate magnitude bin is shown in yellow dotted line, and the faintest bin is shown in green dash-dotted line. To highlight the light retention in the outer region, the profiles are zoomed-in beyond 100 kpc from the galaxy centre.
