Field of view of the Euclid observations of the ERO Fornax cluster (ERO-F) presented in this paper. North is up and east is to the left. The stack of four VIS images is shown in translucent grey above a colour image from the Fornax Deep Survey (FDS), which shows the brightest cluster galaxy NGC 1399 just off the Euclid pointing in the south-east. The ERO-F field includes ten massive galaxies previously targeted by the ACSFCS (small inset images) around which about 900 GC candidates were identified by that survey (yellow dots: GC probability p_GC > 0.95; Jordán et al. 2015). The galaxy FCC161 (NGC1379) is among the galaxies in the ACSFCS survey; however, its final HST data are corrupted. Therefore, no ACSFCS GC catalogue for this galaxy has been published. Additionally, the Euclid FoV overlaps with the position of about 30 dwarf galaxies (large green dots; Venhola et al. 2018, 2022) and about 602 spectroscopically confirmed GCs (red dots; references in the text).
