Numerical simulation of the probability density distribution of rpr, where rp is the projection on the plane of the sky of the distance r between members of randomly oriented pairs (for a fixed 3D r value). The number of simulated pairs is N ≈ 10 000. Apart from statistical fluctuations, the obtained probability distribution agrees with the theoretical expectation (continuous red line, see text).
