(Top) Structure factors $S_M\left(q\right)$ deduced from the SAXS $I\left(q\right)$ data, using the 5-mg/mL data for the measured form factor $P_M\left(q\right)$. (Bottom) $S_M\left(q\to 0\right)$ vs. ϕ from both SLS and SAXS agree with hard-sphere models, but do not distinguish the polydisperse PY, Schulz-distributed mixture model with $p=0.20$ (black) from either the monodisperse PY (green) or the Carnahan–Starling (red) models.
