Table 6: The five spectroscopic binaries (SBs) and their orbital elements. Columns for the first part of the table (literature data): (1) HD number; (2) periastron date T0 (HJD); (3) period P (days); (4) primary orbital semi-amplitude K1 (km s-1); (5) secondary orbital semi-amplitude K2 (km s-1; only for double-lined spectroscopic binaries, i.e., SB2s); (6) systemic velocity $\gamma $ (km s-1); (7) orbital eccentricity $\epsilon $ (see the footnote to the table for literature sources). Columns for the second part of the table (data from this study): (1) HD number; (2) exposure number (Table 3); (3) instantaneous radial velocity (km s-1); (4) primary component prediction using the ephemeris provided above (km s-1); (5) secondary component prediction using the ephemeris provided above (km s-1; only for SB2s).
