RVs of TOI-1438. Top: The HARPS-N (blue) and HIRES (orange) RV time series with the best-fitting three Keplerian model in grey with residuals shown in the panel below. Lower: The phasefolded RV curves for planet b (left) and c (middle) as well as signal d (right). The best-fitting models are shown as the grey lines with the shaded area denoting the 1 and 2σ intervals in the K-amplitude. Residuals are given below. -- astro-ph.EP
