     32The models are based on the papers by Akcasu *et al.* [1] and by 
     33Hammouda [2] assuming the polymer follows Gaussian statistics such 
    3434that $R_g^2 = n b^2/6$ where $b$ is the statistical segment length and $n$ is 
    3535the number of statistical segment lengths. A nice tutorial on how these are 
    36 constructed and implemented can be found in chapters 28 and 39 of Boualem 
    37 Hammouda's 'SANS Toolbox'.

     39In brief, the macroscopic cross sections are derived from the general forms 
     40for homopolymer scattering and the multiblock cross-terms while the inter, 
    4141polymer cross terms are described in the usual way by the $\chi$ parameter.

    4848* **Component D is assumed to be the "background" component (ie, all contrasts 
    4949  are calculated with respect to component D).** So the scattering contrast 
    50   for a C/D blend = [SLD(component C) - SLD(component D)]\ :sup:`2`. 
     50  for a C/D blend $\rho_{C/D} = [\rho_C - \rho_D]$\ :sup:`2`. 
    5151* Depending on which case is being used, the number of fitting parameters can 
    5252  vary.
