Notes. Results for the analysis of the Kepler-9 system with TRADES using the masses, the period, the eccentricity, the argument of pericenter, the mean anomaly of both planets, and the longitude of node of Kepler-9c as fitting parameters.
Parameters from the SOM of Holman et al. (2010).
Analysis of TRADES with initial parameters and T0s from Holman et al. (2010, SOM). Transits and RVs fit.
Analysis with TRADES+PSO+LM and T0s from Mazeh et al. (2013). Initial parameter boundaries were large enough to contains both solutions K9-I and by Holman et al. (2010). We fit only the transit times, and ignored the six RV points.
