Notes. Table after Fabry et al. (2025) (Table C.1 and C.2). For each system, the first (second) line gives the mass, radius, effective temperature and relative overflow for the primary (secondary). Values marked by ^† denote that M₁ is adopted, from which M₂ follows via q and the radii via Kepler’s third law and the fractional radii from the photometric solution. The horizontal line distinguishes between the systems in the Milky Way and M31 (above) and the systems in the Magellanic Clouds (below).
