Remarks

12 May 2012/ From TTVs, the upper mass limit for a potential moon is 0.021MPl (Nesvorny et al. 2012).
The upper mass limit 6M Jup is inferred from stability condition of the multiplanet system (Nesvorny et al. 2012).
The inclination, i, is defined relative to the reference plane that is 90° tilted to the sky plane, and rotated so that Ωb = 270° (all longitudes measured relative to the line of sight; hereafter transit reference system). The orbital inclination of KOI-872.01 relative to the transit plane is ib = 0.97°, as determined from the transit fit.
