Top panel: cumulative magnitude distribution N(< H) of the Wasserburg family members. The black symbols are all 8 known members (including the largest asteroid (4765) Wasserburg shown by the diamond), the blue symbols provide the simplest variant of the debiased population. This was obtained by incrementing the population by 1/p(H_i+1), when stepping from absolute magnitude H_i to H_i+1 (i = 1,…,N_obs); the observed (biased) population increments by one by definition. The gray line is an approximate local power-law representation N(< H) ∝ 10^γH near H ≃ 19 with γ ≃ 1.4. The top abscissa indicates an approximate size computed from H with an assumption of p_V = 0.3 value of the geometric albedo. Bottom panel: Detection probability p(H) of Wasserburg members as a function of H during the phase 2 operations of CSS based on analysis of geometric and photometric detection factors run on a large synthetic population of Wasserburg members. We find that p = 1 up to H ≃ 18.3 magnitude, which sets the limit where the Wasserburg population is complete (dashed line on the upper panel). Beyond this limit p decreases to zero at about 20.5 magnitude.
