Characteristic radii ratios (r_10%/r_50%, i.e., deprojected radii containing 10% and 50% of the stars) as a function of the completed lifetime fraction for simulations with different a) IMBH masses, b) black-hole retention fractions, and c) primordial binary fractions. All models contain 128k particles, except for the binary-fraction models, which are limited to 64k stars. The dashed lines indicate the r_L,10%/r_L,50% (deprojected radii containing 10% and 50% of the mass) evolution when taking the Lagrangian radii.
