Establishing the lunar crater chronology (i.e., surface age vs. crater density) relies on the lunar production function (PF; the formation rate of craters as a function of crater diameters), because a PF enables the conversion of a measured crater size-frequency distribution (SFD) to a reference crater density (e.g., N(1), the cumulative density of …
