Note (1): Barycentric Julian Date is computed directly from the UTC time
          without correction for leap seconds.
Note (2): Relative RVs, with {gamma}_RV subtracted (See Table 3).
Note (3): Internal errors excluding the component of astrophysical/instrumental
          jitter considered in Section 3.
Note (4): The facilities used are defined as:
    FEROS = Fiber-fed Extended Range Optical Spectrograph/MPG 2.2m
