Kepler's new multiplanet systems

Click here for Fabrycky, Ford, Steffen, et al. 2012, ApJ accepted, a paper using simple physical models of transit timing variations to confirm 4 planetary systems.
If you'd like to have a go at them yourself, here's the timing data (sorry, the first arxiv posting had these wrong).

Here are plots of the simple models for other confirmed systems: Kepler-23 Kepler-24 Kepler-25 Kepler-26 Kepler-27 Kepler-28

The official Kepler news feature is here, and below is a visualization of all the multi-transiting systems known:
