(a) Difference in absorption and emission line peak velocity around 1318 nm plotted against the stellar velocity, (b) The same for stellar velocity minus emission line velocity, (c) Emission line velocity versus stellar velocity, assuming the emission line has a rest wavelength of 1317.37 nm. Results with the same stellar velocities are from repeat observations of a given star. Purple points are from Gaia DR2 with Red points from Gaia DR3 for HD 160065.
