a Eight major source craters of the CE-5 samples with ages < 2 Ga outside the P58/EM4 unit. b 2171 source craters inside P58/EM4 unit. c 1223 visible craters within the CE-5 landing region of 2 km across. The two most important contributors are labeled in yellow: Xu Guangqi (C1) and C2. The red star represents the CE-5 landing site. d Size-frequency distribution of 1223 visible craters shown in (c) (red dots). The blue line and shaded region represent the CSFD constructed from the empirical density function (EDF)67 and its 1σ uncertainty, respectively. The 2.03 Ga isochron calculated from the NPF (black line) is shown for comparison (extrapolated to 2 m, shown as the dashed line). The population of small craters with \(D\) < 85 m fall below this isochron, indicative of a large number of erased craters.
