Top: specific angular momentum in units of a²Ω_orb for the donor, the accretor, and the first three Lagrangian points as a function of the mass ratio. Bottom: volume equivalent radii for the donor corresponding to the L₂ and L₃ equipotentials. Volume equivalent radius for L₂ is taken from the fit of Marchant et al. (2016), which due to small errors in the fit results in a slightly larger value than the radius for the L₃ equipotential at q = 1.
