RVSPY and TESS data for HD 38949. The panels show (from top to bottom): the RV time series, the relation between RV and BS, the GLS periodograms of the RVs and of the photometric data (measured by TESS), and the TESS time series. All data products of the RVSPY programme are shown in black, all TESS data products are shown in red. Horizontal lines in the GLS periodogram of RVs reflect the 0.1%, 1% and 10% false alarm probabilities (from top to bottom). The corresponding false alarm probabilities of the TESS data GLS periodogram are all merged in the dashed line at the bottom of the periodogram, owing to the large number of the TESS data points.
