All other parameters of the model are fixed. LSH = 0.9 nm, LSC = 1.5 nm, SH = 404 e nm -3 , sc = 265 e nm -3 , core = 234 e nm -3 and maximum volume fraction of particles 0.00168. The errors have been estimated using standard deviations obtained by boot strapping and using t-student for a 95% confidence interval.
