RV precision on the RVs of each spectral line as a function of the R Pearson correlation coefficient between the RVs of each individual line with the RVs measured on all the lines, as shown in Fig. 5. The blue selection corresponds to spectral line for which the absolute R correlation coefficient is below 0.2, and therefore to lines that does not seem to be strongly affected by stellar activity. The red select includes lines for which the correlation is stronger than 0.6, and therefore lines that are sensitive to activity.
