And the Winner is…

September 18th, 2006

I’ve evaluated the fits submitted for the first Systemic Challenge radial velocity data set, and the winner is Chris Thiessen.

In addition to being dynamically interesting, the configuration proved to be very tough to crack. The challenge 001 system is one where a Keplerian model can reach a low chi-square, which then skyrockets when the planets are actually integrated through their orbits.

I’m travelling today, without full access to the Internet. In the next day or so, once I get back to the office, I’ll put up a more detailed post which looks at what’s really going on in the first challenge system. We’ll also release the second challenge data set (which is equally interesting, but a lot more tractable).
