Notes. The corresponding abundance profiles are shown in Fig. 5. We note that models with fvol = 0.4 have the same porosity length h* = 2.5 × 1013 cm as the one-component models with fvol = 0.2, l* = 5 × 1012 cm and fvol = 0.4, l* = 1 × 1013 cm. Changes larger than one order of magnitude are in boldface.
