Dimensionless quantities for a triple system with an arbitrary tertiary mass (m₃) and outer orbital period (P_out). The system includes an inner circular binary with masses m₁=m₂ = 55 M_⊙ and an orbital period of 1.1 d, at a metallicity Z = 0.00042, evaluated at the ZAMS. The dark grey region indicates dynamically unstable triples. We display the inner to outer orbital angular momentum ratio (η:=L_in/L_out, top panel) and the single-averaging parameter (ϵ_SA, bottom panel).
