Potential interlopers due to deviating radial velocity plotted in the color-magnitude diagram. The blue points show all the members of Sco OB2 that pass the BP/RP excess filter; the orange points are the members with radial velocity in Gaia DR2; the red circles mark the potential interlopers discussed in Sect. 5.2. For reference, the ZAMS model is included as a black dashed line. The data points are not corrected for extinction and reddening.
