Table A.4
Orbital parameters for a sample of intermediate He sdOB stars studied by (Martin et al. 2017) and recent additions (HZ 44, Feige 46, EC 22536–5304). The quantities Rmax, Rmin, and Zmax refer to the maximum and minimum distance from the Galactic centre, as well as the maximumdistance from the Galactic disc. Known zirconium- or lead-rich stars are marked by†.
