Notes. For each observing run, the instrument, the number of spectra N, the HJD of mid-exposure, the average S/N ratio (calculated as the average S/N in the line free regions of [4490 Å–4505 Å, 4953 Å–4968 Å, 6035 Å–6050 Å, 6738 Å–6753 Å]), the range of SNR values, the typical exposure times (in seconds), and the resolving power of the spectrograph are given.
