Color–magnitude diagrams for sources detected around the five galaxies plus the control field (bottom right). Small black dots indicate the resolved sources, while the large black dots are the point sources as determined in Sect. 2.1.2. Globular clusters are depicted in red, inside the magnitude and color limits explained in the text. The number of GC candidates stated for each galaxy is before any decontamination and within the FOV. Green triangles in the NGC 3962 panel indicate UCD candidates (see Sect. 7.4).
