Figure 4: Geometric definitions for the precessional motion of spinning compact binaries [54, 306]. We show (i) the source frame defined by the fixed orthonormal basis ${x, y,z }$ ; (ii) the instantaneous orbital plane which is described by the orthonormal basis ${xℓ,yℓ,ℓ}$ ; (iii) the moving triad ${n, λ, ℓ}$ and the associated three Euler angles $α$ , $ι$ and $Φ$ ; (v) the direction of the total angular momentum $J$ which coincides with the $z$ –direction. Dashed lines show projections into the $x$ – $y$ plane.
