1 Multiple coordinates mean multiple subareas.2 Crater size-frequency distribution absolute model ages are derived using the production function of Ivanov (2001) and the Neukum chronology function of Hartmann and Neukum (2001).3 Epoch boundaries in the Neukum chronology system as recalculated by Michael (2013). See table 1 for epoch boundaries. N, Noachian; H, Hesperian; A, Amazonian; e, Early; m, Middle; l, Late.4 The resurfacing graph gives the reader a first impression of the degree of resurfacing (mild resurfacing vs. intense resurfacing) for any given unit.
