We consider each inclination and one of the longitudes of ascending node as free parameters. For any chosen triplet of these parameters, we compute a new fit. Then we study the long-term stability in a small (in terms of O-C) neighborhood using Laskar's frequency map analysis. We also introduce a numerical method based on frequency analysis to determine the center of libration mode inside a mean motion resonance.
The best orbital solution for the HD202206 is: ------------------------------------------------------------- V0 [km/s] 14.729 +/- 0.001 ------------------------------------------------------------- Inner planet Outer planet ------------------------------------------------------------- P [d] 256.389+/-0.044 1397.445+/-19.056 K [m/s] 564.82+/-1.42 38.08+/-1.21 e 0.431+/-0.001 0.104+/-0.024 a [AU] 0.8053 2.4832 i [deg] 90 90 m [MJup] 16.59 2.179 -------------------------------------------------------------
