Distance at which accreted stars begin to dominate, r_cross, for all galaxies in our sample (black dots) as a function of stellar mass (left panel) and virial mass (right panel). For comparison, we show its median (solid white line), the median stellar half-mass radius, r_50, * (dashed green line), and the median stellar half-mass radius of the adopted galaxy radius, r_glx (solid black line). The typical galactocentric distance beyond which most stars are accreted is ∼8 times larger than the stellar half-mass radius, and close to the galaxy radius definition, r_glx = 0.25 r₂₀₀.
