Fit model: Aggregates (Lorentzian term)
Sc=Sc_scal./(1+(Sc_corr.*q).^2).^Sc_exp;
Parameters:
parameter |
description |
Sc_scal |
scaling parameter proportional to average mass of cluster |
Sc_corr |
proportional to characteristic size of the clusters |
Sc_exp |
exponent with p ~ df/2 |
df |
fractal dimension |
Remarks:
Term to take into account excess scattering at low q which originates from clusters. Sc corresponds to the structure factor of the clusters.
