Notes. Barycentric Julian dates are given in barycentric dynamical time (BJDTDB; Eastman et al. 2010). We split the data into ESPRESSO 1st and ESPRESSO 2nd sets, and treat the two sets independently to account for a potential RV offset that may have resulted from the instrument refurbishment performed between 2019 and 2020. The last two columns provide the exposure time and S/N per pixel at 550 nm. The detrended dataset RVdetrended was derived following the procedure outlined in Sect. 4.1. The errors associated with the detrended measurements account for the jitter. The entire RV data set is available in a machine-readable table at the Strasbourg astronomical Data Center (CDS)
