Distributions of intrinsic parameters depicted in joint distributions showcasing various regimes for the period P on the left. We show the distribution alterations with respect to the mass ratio q and the primary mass M. The upper-left plot illustrates the distribution for M > 1.2 M_⊙, while the lower left pertains to M < 1.2 M_⊙, each highlighting regimes for q > 0.3 and q < 0.3. The top-right plot presents the distribution for the mass ratio q, while the bottom right illustrates the eccentricity distribution, notably demonstrating an abundance of circular orbits.
