Doppler data time-series of HD 23472 obtained with HARPS. The small number of data points (14) by itself is not sufficient to discover the planets, but taking advantage of the a priory knowledge of the TESS transit ephemerids, it enables constructing a two-planet model, which is in excellent agreement with the RV data (see Table 2 for details). As in Fig. 2, the RV uncertainties include the RV jitter.
