Fig. 4.
Left panels: stellar mass as function of projected distance from NGC 1316 (top panel) and colour-magnitude relation (lower panel) for bright spiral galaxies inside the virial radius of the Fornax A sub group. Right panels: size-mass relation (top panel) and effective radius as a function of projected distance from NGC 1316 (lower panel) for all the bright spiral galaxies in the Fornax A subgroup. A least square fit to the data is shown in orange (including NGC 1316) and blue (excluding NGC 1316).
