Notes. We present results for the two modes of the joint posterior, which we define using the inclination angle θ_n. We first report the parameters that directly enter our sampling algorithm: mass ratio q, spin magnitudes χ_1, 2, spin tilts θ_1, 2, spin azimuthal angles ϕ₁ and Δϕ = ϕ₂ − ϕ₁, and direction of the line of sight θ_n and ϕ_n. We also build posterior distributions for the quantities that directly enter our likelihood, namely the projected kick velocity v_∥ and the projected spin-kick angle θ_vχ, ⊥. Finally, we show the measured values of some other derived parameters: kick magnitude v, projected recoil velocity v_⊥, spin-kick angle θ_vχ, observer-spin angle θ_nχ, and observer-kick angle θ_nv.
