Distribution of spin frequencies after ejection from 2P/Encke comet for 1 mm (left), 1 cm (middle), and 10 cm (right) meteoroids. Gas ejection is according to Ma et al. (2002), active fraction of the surface is 50%. The solid vertical line represents median value and dotted vertical lines bound 2σ interval. Small arrows with letters g, c, f denote median values for gravel, clay, and fragments shapes.
