Gini-M₂₀ diagram, based on the r-band Legacy survey image. The orange line sets the division between merger candidates and normal Hubble types (Lotz et al. 2004). The black dotted line separates early-type (E, S0 and Sa) from late-type objects (Sb to Sd, as well as Irr) (Lotz et al. 2008). G49, a late-type galaxy, does not appear on this panel but has (-1.21,0.86) for coordinates, so lies in the “likely mergers” region. The DP/MaNGA galaxies are colour-coded according to their morphology: ⋆ETGs, whose ⋆ ellipticals and ⋆ S0; ⋆ mergers; ⋆ LTGs.
