Comparison between v_eq sin i_★ computed from the HARPS-N FWHM_DRS (x-axis) and those computed with SOPHIE in HE mode (y-axis). Upper panel: orange triangles and light blue dots are the results from SOPHIE HE FWHM_DRS with the K5 and G2 relation, respectively, while the red triangles and blue dots are the results from the corrected SOPHIE HE FWHM_new (y-axis). The black line shows the one-to-one correlation. Lower panel: residuals for the corrected SOPHIE HE FWHM_new only.
