Fig. 2From: A newly revised estimation of bulk densities and examination of the shape of individual Ryugu grainsPlot depicting the axial ratios of 724 Ryugu grains. a Distributions of b/a and t/a ratios of Ryugu grains. Grains plotted in shadowed area are the grains with t/a > b/a. b Distributions of B/A and T/A ratios of Ryugu grains; replot of a. Frequency distributions of the ratios are shown outside of the diagram. Mean B/A and T/A ratios are 0.73 and 0.59, respectively. The shape terminology is based on the classification described in Blott and Pye (2008). Typical grains corresponding to each classification are shown in Fig. 4Back to article page
