Observed RV variations and the best-fit orbital solutions of HD 208897 with its residuals (bottom) to the best-fit-model. The solid red, dotted, and green dashed lines indicate the best Keplerian fit for TUG+OAO, OAO, and TUG, respectively. Dark gray points and blue squares represent data from TUG and OAO, respectively. The offset of 13.63 m s^-1 was introduced to HIDES data. The rms to the fits are 18.13 m s^-1, 4.81 m s^-1, and 20.54 m s^-1, respectively.
