The excluded volume fraction and the interaction radius were used as fitting parameters. Some of the listed χ² values are a bit high, but as can be seen from Fig. 1, the deviations of the experimental data from the model fits are primarily found above 0.15 Å⁻¹, and for that reason, this major part of the deviation does not influence the precision of the calculated parameters.
