Probability density distribution of the ratio m_frag/m_LF (normalized to unit at maximum), where m_frag is the mass/volume of all members up to absolute magnitude 20 without (525) Adelaide, and m_LF is the mass/volume of the largest asteroid (525) Adelaide. The solid/gray histogram for the ℳ2 model, the dashed histogram for the ℳ3 model (all models whose parameters p are within the 99% confidence level of the family population were used).
