Example of the result of RV homogenization on RV standards. Gray dots show the difference between individual spectrum measurements and the reference values of Table 3. The colored symbols are the same RV differences, but aggregated for each RV standard star in the various setups, and are still uncalibrated. The final iDR4 recommended values, obtained from the internal homogenization process, are shown by large black diamonds, which are placed at the average S/N of the spectra obtained for each RV standard star.
