Three orthogonal projections of the distribution of satellite galaxies in centres of DM halos of ~1 Mpc radius in our adopted simulation of C12 (coloured dots). The colour coding indicates the magnitude of a given galaxy. The black dots show the positions of galaxies fainter than M_r = −18 that populate halo and subhalos in the simulation according to the mass function by Giocoli et al. (2010) down to 10¹⁰ M_⊙.
