Notes. The listed properties are taken from Kourkchi & Tully (2017), where formulae and definitions to the parameters are provided. The centre of Dorado coincides with S0 galaxy NGC 1553, which has as close-by companion the BGG NGC 1549. The reported group distance and heliocentric velocity are based on the unweighted averaging of the radial velocities of their members. ( † )Morphological classification of group members divided in early-type galaxies (ETG), late-type galaxies (LTG) and unclassified (Uncl.) (Rampazzo et al. 2020).
