Central area of the Fornax cluster. The globular clusters are denoted as blue dots, UCDs as red dots, and NGC 1399 and two neighboring galaxies are shown as colored plus signs. The dashed black lines denote the borders of the CCD chips and gap areas of the globular cluster sample. For our statistical studies, these are masked out. The green areas are also be masked out in the final study because they host their own GC population. The small green circle locates the position of the UCD with four neighboring GC candidates, which is shown in Fig. 14 in close up.
