Two examples of a satisfactory fit of the observed (gray line and symbols) and modeled (black line and symbols) populations of the Datura family (we show the population except for the largest fragment (1270) Datura). The unbiased, source population shown by the dashed line is assumed to have two power-law segments with cumulative exponents α (large sizes) and β (small sizes) and a break at D_break. In the two cases we have: (i) α = 5.36, β = 2.11 and D_break = 1.08 km (top); and (ii) α = 9.50, β = 2.09 and D_break = 1.24 km (bottom). The source population is transformed to the modeled population by the CSS detection efficiency function from Fig. 15. The magnitude-size relation assumes geometric albedo p_V = 0.24, and the error bars of the observed population are from the magnitude uncertainties in Table 8. The smallest sizes denoted by the light-gray region are heavily biased against detection: B< 0.05 in this case.
