Table B.1.

Results of the HERMES and APOGEE RV monitoring are displayed in columns 3 to 8 and 9 to 11, respectively, and are statistically combined in columns 12 to 14. Columns and σ list the mean RV and the corresponding standard deviation. The probability Prob of the star being in a binary system, from the HERMES data alone (and adopting an uncertainty of 0.07 km s⁻¹) is listed in column 5 (in fact, Prob is the probability integral of the χ² distribution from 0 to the observed χ² value for N − 1 degrees of freedom) are tabulated as well. N denotes the total number of HERMES or APOGEE RV measurements for each star and Δt is the number of days between the first and the last observation. The value F2 in column 13 corresponds to the F2-statistics of the combined HERMES-APOGEE RVs, assuming a 0.4 km s⁻¹ offset between their zero points and a minimum uncertainty on the RVs of 0.09 km s⁻¹ (see text). Columns 15 to 18 correspond to the Gaia DR2 RV measurements, which cover the time span JD 2456863.5 to 2457531.5 (2014 July 25 to 2016 May 23), just prior to the HERMES monitoring thus. The column labelled ϵ lists the expected uncertainty on the Gaia DR2 RV (see text). The column labelled ΔRV under the heading Gaia DR2 corresponds to RV_HERMES − RV_DR2. ΔRV under the heading APOGEE corresponds to RV_HERMES − RV_APOGEE, after applying the zero-point offset of −0.40 km s⁻¹ to the APOGEE velocities. Values in bold face identify binary signatures. The last column summarizes the situation regarding binarity, collecting the diagnostics from HERMES, Gaia DR2, and APOGEE. When the only binary signature is an offset between Gaia DR2 and HERMES, the star is flagged as ’SB?’.
