Halo and subhalo distribution in the projection x-y considering a field of view of 10 Mpc on a side and ±5 Mpc along the line of sight, ΔH = 10 Mpc, for the GadgetX cluster run. Black circles show the location of the centre of all subhaloes within the halo radius R₂₀₀, red triangles are all haloes which, in projection, fall within the halo radius, and magenta crosses are all haloes that, in projection, lie in a ring between 2 and 3.5 R₂₀₀, which we term outer haloes. The blue map is the corresponding region where we simulate the weak-lensing cluster signal.
