I wasn't referring to the ~50Kyr age of the crater, but rather to the likely age of the asteroid collision involving an M-type asteroid that produced the nickel-iron fragment whose orbit later diffused into the inner solar system and produced the Barringer impact. best, Greg Hi Lab Lemming,

I am still fooling around with his code for modeling planetary systems (using Differential Evolution MCMC methods), but we might expand the code to include transits.
