Caption: Figure 7.
Secondary crater diameter as a function of distance from Tycho. The solid red line represents the likely maximum secondary crater diameter (see Table 2 from K. N. Singer et al. 2020) at a given distance from the primary crater. Green points show observed craters. Note that the model line is a 99th percentile regression, and as such, measured craters should mostly fall below this line.
