Cumulative and size-frequency distributions for Class 1 to 7 craters in the study area. Class 1–7 craters (dark blue 5-pointed stars), Class 1–6 craters (blue inverted triangles), Class 1–5 craters (light blue triangles), Class 1–4 craters (yellow circles), Class 1–3 craters (orange squares), and Class 1–2 craters (red triangles). Cumulative crater SFD plots for Class 1 to 7 craters with pseudo-log bins. Hartmann and Neukum's (2001) chronology function and Ivanov's (2001) production function (gray line) are plotted, with gray areas indicating epoch boundaries (Michael 2013)
