Notes. Column 1: group name. Columns 2 and 3: number of bright galaxies in the group (Mg < −17) and fraction of ETGs. Columns 4 and 5: integrated magnitude and luminosity in g band of the IGL. Columns 6 and 7: fraction of intragroup light divided by the BGG luminosity and total luminosity of the group. Column 8: total HI mass associated to the group. Column 9: distance of the group used to estimate the total HI mass; for NGC 5018 by Kim et al. (1988), for NGC 1533 by Kilborn et al. (2005) and for IC 1459 by Kilborn et al. (2009).
