Locations of the analyzed 1° × 1° Fornax fields (highlighted with gray), plotted over the FCC galaxies (the black points, Ferguson 1989b) with mB< 18 mag and the member classification 1 or 2 (confirmed or likely member, respectively, in Ferguson 1989b). The blue dashed circle is the virial radius 2.2° (or 0.7 Mpc at the distance of Fornax cluster) adopted from Drinkwater et al. (2001a). The red cross shows the cD galaxy NGC 1399 (see Iodice et al. 2016) in the core of the Fornax cluster, and the blue cross shows the elliptical shell galaxy NGC 1316 (see Iodice et al. 2017), which is the central galaxy of the Fornax-SW subcluster.
