BBH mass ratio q and black hole separation D₁₂ for our set of hydrodynamical simulations.

$\frac{D_{12}}{r_{g 1}}$ $\displaystyle\frac{D_{12}}{r_{\mathrm{g1}}}$	500	10³	1.5 × 10³	2 × 10³	3 × 10³	6 × 10³
q	9 × 10⁻⁴	1; 0.3; 0.05; 0.005	1; 0.3; 0.05	1; 0.3; 0.05	1; 0.3; 0.1; 0.01	1

Notes. The separation is expressed in units of the primary black hole gravitational radius, r_g1. Our simulation sample exhibits a binary separation ranging from 499.55 r_g to 3 × 10³r_g, where r_g is the binary gravitational radius defined as r_g = (1 + q)r_g1.
