Best-fit solution of the complete Hobson population to the magnitude limit H₂ = 19 and its comparison to the observed population. The single power law ℳl model with the free parameter representing the slope γ. The best fit value is γ = 0.81, and the corresponding . The green symbols are the currently known population of Hobson family members from all surveys, the open black circles are the members detected during the phase 2 of CSS ({}). The red line is the complete model ({}), the blue line is the biased model ({}; the solid part of the blue line has N′_CSS objects, the same as the number of detected objects beyond the branching magnitude , the dotted part is the continuation of the biased population not used for the least-squares fitting in Eq. (2)). The upper abscissa shows an estimate of the size for the geometric albedo value p_v = 0.2.
