Notes.
The true mass (mp) is reported for GJ 876 b, c, for the transiting planets GJ 436b and GJ 1214b and for all microlensing detections. The masses given for GJ 876d assumes a 50 orbital inclination. We give minimum masses GJ581b, c, d, and e, and dynamical consideration restrict coplanar systems to i > 40°. Uncertainties in planetary masses usually do not include the stellar mass uncertainty.
Instead of 1σ uncertainties, we quote 90% confidence intervals from Batista et al. (2011).
