Comparison between HARPS-N RVs measured with the HARPS-N DRS from CCFs (open red circles) and with serval (open green circles). The red crosses show the difference between the two data-sets. The five points in which this difference is significantly negative correspond to exposures that were prematurely terminated, and which are not correctly processed by DRS. Both data-sets have been averaged to zero without considering these five points. The difference between the two data-sets has a standard deviation of 0.92 m s⁻¹ (excluding again these five points).
