\tablefoot {$N(D > 1)$ is the total number of $D > 1$~km Plutinos impacting Charon over 3.5~Gyr,
$\tau(D > 1)$ the timescale on which these impacts occur, $D_{{\rm i,Max}}$ the  largest Plutino expected to have struck Charon during the past 3.5~Gyr, 
$C(D > 1)$ the total number of $D > 1$~km craters on Charon produced by Plutino impacts over 3.5~Gyr, and $D_{{\rm c,Max}}$ the largest crater diameter on Charon.}
