Convergence maps of the three considered random projections of a cluster, namely halo 4 at z = 0.22. The left, central, and right panels show the projections along the z-, y-, and x-axis coordinates of the re-simulated box. The source redshift of the map is fixed at z_s = 3. The size of the field of view is 5 Mpc (3.4 h⁻¹ Mpc) on a side and 10 Mpc along the line of sight. The map resolution is 2048 pixels on a side.
