Notes. The characteristics of the 2-σ detection curve for each asteroid (α is the slope of the function, rlim separation between both noise regimes dominated by the Poisson noise close to the primary at r < rlim and by the [detector + sky] noises at r > rlim. At r > rlim the detection function can be approximated by a flat function with a value of Δmlim). The radius of the Hill Sphere calculating based on consideration about the size and density of the asteroid (see text) is calculated. The minimum size for a moonlet to be detected at 1/4 and 2/100 RHill is also indicated.
