Numerically evaluated distribution of force fluctuation, 𝒫(δf), in different shells of increasing radius (clockwise from top left, r = 3.1 × 10⁻², 7.2 × 10⁻², 0.38, 1.3, 6.9, and 54.8 in units of r_c) for a Plummer model with N = 10⁶ and 10² realizations (grey dots). The blue dots mark the PDF averaged over said ensemble, while the red curve is the corresponding the Holtsmark distribution (15) computed for the local value of the density, ρ(r), and average number of particles in the shell, $\overline{N}$.
