Rotated 2D Gaussian representing the distribution of EBs in the (vbroad, period) plane. Line equation: log V = A log P + B, where A = −0.948 ± 0.026 and B = 1.952 ± 0.005. Black squares mark systems with |e cos ω| > 0.1, which are not fitted by the algorithm. The plot shows 100 parameter sets sampled from the MCMC chains after convergence. The red lines represent the Gaussian’s major-axis orientation, and the red ellipses show the distribution 3σ region. A full derivation is provided in Appendix B.
