Cumulative distribution N(< H) of the absolute magnitude H for known Hobson family members. Left panel: all members included: the red and blue diamonds denote the two largest remnants (18777) Hobson and (57738) 2001 UZ160, and filled circles show small members in the family. The gray line shows the power-law relation N(< H)∝ 10^γH for γ = 0.95, which approximates the distribution of small members. Right panel: the second largest member, (57738) 2001 UZ160, is excluded from the distribution: the red diamond denotes (18777) Hobson, and the filled circles are smaller fragments in the family. The power-law relation N(< H)∝ 10^γH has now γ = 1.15 (simply as an effect of removing the second largest body from the sample and linear-logarithmic scales on the axes). The upper abscissa in both panels provides an estimate of the size, assuming the geometric albedo p_V = 0.2 (a plausible value for S-type asteroids).
