Left panel: position of the three dwarf galaxies (solid red circles) reported in this study with respect to the spiral NGC 253. The red circular line corresponds to the area explored by the PISCes survey (Toloba et al. 2016) extending up to ∼150 kpc from the centre of NGC 253. The total field of view of this image is 450′×480′. Right panel: full colour version of the image cutouts obtained with LEGACYPIPE for Do II, Do III, and Do IV. North is up and east is left. The field of view of all these image cutouts is 3.3′×3.3′.
