The radial migration of KCD stars born at different redshifts is depicted by plotting their birth radius against the radius at the final, |$z = 4.4$| snapshot. Stars above the red dashed line migrated outwards, while those below migrated inwards. We utilize 150 bins, evenly spaced in logarithmic space, for both radii, spanning from 0.001 to 5 kpc, and apply a strict threshold of at least 50 star particles per bin to ensure we recover general trends and exclude outliers.
