Environment of our MUG sample is compared with the general distribution of GAMA massive galaxies. This is depicted by a blue colored Kernel Density Estimation, using individual datapoints where the density of datapoints is too low. Our MUG sample is colour and size coded as in Fig. 11, split according to the Sérsic index into disk-like (n < 2.5, blue) and spheroid-like (n > 2.5, red). The group dynamical masses and cluster-centric distances distances are taken from the G³C catalogue of Robotham et al. (2011), see text for details.
