Table A.4: The LEV dataset used in this sample, consisting of 16 binaries with orbital elements (SB1 or SB2), and 23 radial velocity variables (RVV), for which no orbital elements are available. Left: the 16 spectroscopic binaries with orbital elements among the confirmed members of Sco OB2, in the LEV dataset. LEV observed 53 confirmed members of Sco OB2, of which 8 SB1s, 8 SB2s, 23 RVVs, and 14 targets with a constant radial velocity. Right: the 23 RVVs. Note that several of the RVVs may not be spectroscopic binaries, as radial velocity variation may also be caused by line profile variability.
