Difference between the eccentricity at binary formation (e_b) and the initial eccentricity of the merger (e₀) as a function of the initial galactic merger orbital eccentricity (e₀). The horizontal dashed line at (e_b − e₀) = 0 highlights where the points should be if there were a 1:1 correlation. Empty and filled dots represent data from the LR and HR runs, respectively. The shaded faint red area highlights the region where e₀ > 0.9, while the shaded darker red area defines the region where e₀ > 0.98.
