Notes. The second column indicates the number of data points (nightly averages) per target, the third column the time span Δt in days, and the fourth column the number of planets assumed in the model. The dispersion (rms in m s−1) of the residuals to the fit of the radial-velocity data is given for all three versions of the DRS, for the full data set (Global), and the data sets before and after the fiber change separately.
