RVs of HN Lib over time. The red, green, and yellow markers depict the CARMENES VIS, HARPS, and HIRES RV data, respectively. The black lines show the median of 10 000 samples from the posterior of the final 2P_{(36d-ecc, 113d-circ)} + dSHO-GP_(96d) model. Grey shaded areas denote the 68%, 95%, and 99% confidence intervals, respectively. The purple line shows the GP part of the model. The instrumental RV offsets were subtracted from the measurements and the models. Error bars of the measurements include the jitter added in quadrature. The residuals after subtracting the median models are shown in the lower panels of each plot.
