We thank Bill Bottke for kindly providing us with the original code for calculating the evolution of crater populations used in the Greenberg et al. (1994; 1996) work, and Dan Durda and an anonymous reviewer for their helpful reviews and comments. D.P. O'Brien was supported by a NASA Graduate Student Researchers Program fellowship and grant NAG5-11497 from the NASA Planetary Geology and Geophysics Program while at the University of Arizona, and a Poincaré Fellowship while at the Observatoire de Nice.

N2 - O'Brien and Greenberg [O'Brien, D.P., Greenberg, R., 2005. Icarus 178, 179-212] developed a self-consistent numerical model of the collisional and dynamical evolution of the main-belt and NEA populations that was tested against a diverse range of observational and theoretical constraints. In this paper, we use those results to update the asteroid cratering model of Greenberg et al. [Greenberg, R., Nolan, M.C., Bottke, W.F., Kolvoord, R.A., Veverka, J., 1994. Icarus 107, 84-97; Greenberg, R., Bottke, W.F., Nolan, M., Geissler, P., Petit, J., Durda, D.D., Asphaug, E., Head, J., 1996. Icarus 120, 106-118], and show that the main-belt asteroid population from the O'Brien and Greenberg collisional/dynamical evolution modeling is consistent with the crater records on Gaspra, Ida, Mathilde, and Eros, the four asteroids that have been observed by spacecraft.
