Notes. The midpoint of the observation in the abbreviated barycentric Julian date (BJD′ = BJD − 2 450 000.0), exposure times of each individual spectrum, the signal to noise at the échelle order 69, and the derived radial velocities for the high (RV1) and small profile (RV2) in the cross correlation function. We adopt the 2 σ-threshold of 140 m s−1 of the night-to-night stability as the typical uncertainty of the measurement. The horizontal line marks the beginning of the observations in 2015.
