Subaru/IRD radial velocities obtained in the YJ- (grey squares) and H- (black circles) bands. The data are plotted with both their original error bars (thick solid lines) and the error bars enlarged by the best-fit jitter terms (thinner transparent lines). The top panel displays the data as a function of time. The solid red line shows the 2-planet model generated from the posterior median, while semi-transparent red lines show 25 models randomly drawn from the posteriors. The residuals around the median solution are shown in the second panel. The two lower panels show the data folded on the orbital periods of planets b and c, respectively, after removing the RV component from the other planet.
