Notes. The HJD is given at the middle of the exposure; the seeing is the averaged seeing corrected by airmass; the slit position angle (PA) was not kept fixed during observations and each 2 × 1500 s exposure samples a PA range of about ± 7 deg, as listed; the radial velocity (RV) is determined based on a fit to the Li I (λ 6708 Å) line in the averaged spectra of each night.
