Fig. 4From: Timing and duration of mare volcanism in the central region of the northern farside of the MoonCumulative crater size-frequency distribution of the mare deposit in Buys-Ballot. Solid curve indicates the crater production function polynomial fitted to the observed CSFDs (Neukum, 1983; Neukum and Ivanov, 1994). Error bars are calculated by log(N ± N1/2) / A, where N is the cumulative number of craters and A is the counted area.Back to article page
