The CMDs of all point-like sources meeting the selection criteria (Section 3), with S/N > 5 and falling within 2 r eff of the center of each target galaxy. Points (red or black) indicate sources that meet the concentration index criterion and black crosses are those that fail it. The gray rectangular outline shows the color–magnitude parameter space used to select GCCs, and red points are those sources that meet all the criteria.
