Results of the RadVel MCMC Keplerian circular orbital model with one planet of the SPIRou RV time series. Each column represents the results for each set of data reductions: LBL at |V_tot| > 10 km s^–1, wPCA, and Wapiti. Panel a shows the RV time series, panel b displays the residuals as a function of time, panel c plots the phase-folded RVs together with the best fit model (blue line), and the panel d displays the corner plots of M_b sin(i) and semimayor axis of the planet detected. The red circles in panel c are the RVs binned in 0.08 units of the orbital phase. In all RVs, the RadVel RV jitter σ_SPIRou described in Table 9 is added in quadrature to the RV uncertainties. The orbital, planet, and fit parameters of the models are summarized in Table 9. Corner plots of the circular fit are provided in the Appendix (Figs. D.3, D.4, and D.5). Our baseline solution is the model based on the SPIRou wPCA data set.
