Table A.1

Number of pairs in the Magneticum simulation cosmological volume Box2/hr at z = 0.07 for different selection criteria based on the pair members three-dimensional (3D) and projected (2D) distance and mass ratios.

Notes. The 2D distance d_2D considers any projection out of the three main Cartesian directions, that is, we report the number of pairs for which the projected distance on at least one of the projection planes is < 5(10) Mpc (i.e. d_xy < 5(10) Mpc V d_xz < 5(10) Mpc V d_yz < 5(10) Mpc).
