A) Cumulative SFD of boulders 7 m per km2 over the southern surface of 67P. Vertical error bars indicate the root of the cumulative number of counting boulders, divided by the area computed from the 3D shape model of 67P. The continuous line is a fitted regression line to the data, and the power-law index of the SFD is −3.6 ± 0.2. The bin size is 1 m. B) Histogram presenting the normalized frequency in percentage per boulder size. As above, the bin here is 1 m.
