Orbital analysis of HIP 15429. The top panel shows the RV time series, with data points colour-coded by the instrument used for observation, and RV orbit models computed from posterior samples (blue lines). The lower-left and middle panels show the posterior distributions for the orbital period, P, and eccentricity, e. The MAP model is indicated by the solid black line. The phase-folded RVs and residuals from the MAP model are shown in the right-hand panels.
