Median binary separation relative to the particle size as a function of particle inflation factor f^* used in the simulation that formed the binary. The left-hand axis (blue) shows separation relative to the inflated particle radii, and the right-hand axis (orange) is relative to the uninflated physical particle radii. The error bars indicate the standard error for each set of data points from simulations with a given f^*. Power-law fits are drawn to guide the eye.
