Upper panel: CRIRES infrared RV measurements of HD 59686 A. The black solid line shows the best Keplerian fit obtained from the Lick data alone. Bottom panel: residuals of the CRIRES RVs from the optical fit. The value of the rms is ~59  m s-1, which is consistent with the large infrared RV errors. The mean error of the CRIRES data, with a jitter of 19.83  m s-1 added in quadrature, is ~45  m s-1.
