Notes. In this table N. prim is the number of primaries with amass >0.8 M⊙. The sizeX, Y, Z are the quadratic sum of the standard deviation of the X, Y, and Z Cartesian coordinates on the galactic frame (X is towards the centre of the Galaxy), respectively. Gaia lim is the mass corresponding to a magnitude of G = 19.
