  1. Age boundary from Hartmann and Neukum (2001), crust thickness from Neumann et al. (2004), curvature from Ruiz et al. (2006), and heat production elements from Taylor et al. (2006)
  2. Negative curvature indicates the compressional field. Lower value calculated elastic thickness for strain-rate of 10−19 (s−1), and higher for 10−16 (s−1)
