Notes. The third column indicates the instrument (F = FEROS@2.2mESO, L = échelle@LCO, C = REOSC@Casleo), while the fifth provides the signal-to-noise ratios (S/N) of the spectra near 5000 Å. The systematic differences in CASLEO EW measurements of the He i 5876 line are probably produced by the scattered light in the background (not perfectly subtracted). For this detector, we also note that this line and the neighbouring interstellar lines appear at the edge of the detector, hence they are less reliable. There are some values missing for CASLEO data: the Hα line is outside the range of the spectrograph and, in a few other cases, lines were too noisy to be reliable hence their measurements are not quoted here. Typical errors on RVs are about 1 km s-1 for LCO and FEROS data and 3–5 km s-1 for CASLEO data, while those on EWs are below 5% in the LCO and FEROS spectra and between 5 and 10% for the CASLEO spectra.
