Iteration filling model

Fig. 4 Experimental order parameters, S, of NH bond vectors in GB3 derived from iterative Direct Interpretation of Dipolar Couplings (DIDC) using all six sets of RDCs. The red line marks the order parameters derived from relaxation. Filled symbols represent residues for which the fully anisotropic model was required to get a satisfactory fit to the data, while, for open symbols, the isotropic internal motion model was able to fit the RDCs to within the experimental noise.

The HBG formulas, also known as the asymmetric Bruggeman formulas, are obtained assuming that the MG model is exact at low filling factors and then, following an iterative procedure, adding a small fraction of particles at each step [18, 19]. This model is recognized as valid at least for/< 0.8. 

Thus the iterations go down to a very small scale A, as in the Bidaux et al model for FCD-I s filling. It is difficult to imagine some other cut-offs of the iteration because in...
