Initial distributions of the inner- (blue) and outer (red) semi-major axis for our fiducial model and three model variations. The solid black lines represent the ZAMS population, consisting exclusively of initially stable, non-interacting hierarchical triple stars. The lighter colours correspond to the population before excluding dynamically unstable systems and systems that are Roche-lobe filling at birth. To enhance the features in the plot, we have cut off the top part of the distribution for model a_in & a_out-Sana. The bottom panel shows the initial sampling distributions of the fiducial model and the Sana distribution.
