Low-resolution grid parameterizations using 10 grid variations for a two-dimensional grid covering the sedimentation coefficient range from 1 to 10 S and the anisotropy range for frictional ratios from 1 to 5 given by (A) straight-line models; (B) increasing sigmoid models; and (C) decreasing sigmoid models. Higher resolution is achieved by either iteratively increasing the resolution in a subsection of the grid, or by using denser grids.
