Appendix A: Comparisons between different chains.
In order to lighten the text, here are placed the results of the Markov Chains using various starting hypotheses and from which we estimated upper limits on eccentricity and long term radial velocity trends.
Table A.1 compares the results in χ2 by instrument and during the Rossiter-McLaughlin effect for eights chains. From this we concluded that the eccentric orbit model is compatible with the circular, that a drift that can be fitted is statistically indistinguishable from zero, but that we detect an anomaly in the reflex Doppler motion, corresponding to the location where the Rossiter-McLaughlin effect is expected.
Table A.2 explores the parameters issued from chains where the Rossiter-McLaughlin effect was fitted in order to make sense of the results and see their dependency on initial hypotheses.
Comparison of the results in χ2 by instrument and during the Rossiter-McLaughlin effect 2 different families of chains: having no prior on V sin I, and not fitting the Rossiter-McLaughlin effect.
Results from various Markov chains of the three parameters which control the shape of the Rossiter-McLaughlin effect.
