VAR: exhibits a significant RV variation, but without any conclusion about the origin. The star is flagged as SB1 when there is evidence for a global, coherent motion of the lines without marked changes in their profile, which is strongly reminiscent of an orbital motion; LPV: exhibits changes in the line shape, most probably due to pulsations, but other possibilities (e.g. rotational modulation of a spotted photosphere) cannot be ruled out. In each case, a confidence level is assigned (see Table 2).

M17: identified as SB2 based on GES iDR4 data by Merle et al. (2017); H08: SPB candidate according to Handler et al. (2008); SH05: confirmed β Cep star (Stankov & Handler 2005); EB: β Cep variable in an eclipsing binary (Engelbrecht & Balona 1986); P16: strongly magnetic, He-rich star (Przybilla et al. 2016); H17: lack of SB2 signature, but rotational modulation because of a spotted surface (Hubrig et al. 2017).

GIRAFFE RVs inadvertently not measured, but SB1 status obvious.
