Expected behavior of the small-to-large grain size ratio of silicate (top panel) and carbonaceous dust (bottom panel) versus the silicon and carbonaceous dust abundances, respectively, of anomalous sight lines; continuous line holds for Si grains of the whole sample y = (0.43 ± 0.06)x + ( − 1.55 ± 0.13) with dispersion 0.34 and correlation index 0.60. Symbols are the same as in the previous figures.
