Notes: The quality flag "2" refers to RV curves of poor quality because either of unstable fit, insufficient coverage or small number of data points. We list the pulsation period that we have derived for each star and which is used in the Fourier fit, see Sect. 3 for details. RV References: 101: Anderson et al. (2024), 104: Pont et al.
