Distribution of crater diameter ratios for craters common to the Y. Wang et al. (2021) catalog and two reference catalogs. Panels (a) and (b) show histograms of the diameter ratio (D_Wang/D_Ref) of the north and south poles, where the reference catalog is S. J. Robbins (2019) (blue) and L. Rubanenko et al. (2019) (red). The number of craters common to all three catalogs and included in this analysis is indicated in parentheses. Histograms are normalized and plotted using 1%-wide bins. The inset tables show the mean (μ), mode, median, and standard deviation (σ) of each distribution. Plotting style is adapted from S. J. Robbins (2019).
