Notes. Column 1 – Fornax A subgroup members from Ferguson (1989); Col. 2 – Total magnitude in g-band derived from the isophote fit. Values were corrected for the Galactic extinction, using the absorption coefficient by Schlegel et al. (1998); Cols. 3 and 4 – Average g − r and g − i colours; Col. 5 – Effective radius in r-band, in arcsec; Col. 6 – Projected distance from the galaxy centre in degree, that is, from NGC 1316 (FCC021); Col. 7 – Absolute magnitude in i-band, derived using the distance modulus from NED and Tully et al. (2009); Cols. 8 and 9 – Stellar mass and mass-to-light (M/L) in i-band.
