VST mosaic in g-band of the Fornax A subgroup covering 3 × 2 deg². The red dashed circle is an approximate measure of the virial radius of the group, which is ∼1 deg² (Drinkwater et al. 2001a). The black dashed circle (r = 0.58 deg) is the region where the IGL is estimated. All galaxies part of the Fornax cluster and Fornax A subgroup, taken from Venhola et al. (2019) are indicated. The red cross indicates NGC 1316. Bright galaxies (m_B < 16 mag) are represented with blue circles. Red diamond represents dE (m_B < 16 mag), pink squares represent dE (m_B > 16 mag), and purple squares represent dl (m_B > 16 mag).
