Various properties of charged species and magnetic diffusivities radial profiles shown for models S1 (black), S2_MRN (red), S3_MRN (blue), S4 (green), and S5 (lilac). The colours refer to the same models in all following figures. Plots show, from left to right, the density of ion vs. radius, the relation of electron density to the ion density, and the relative abundances of charged dust to the ion density (bottom).
