Semi-analytic and measured enrichment in our hydrodynamical models (MRN excluded) against the initial Stokes number. The lines represent the semi-analytical development using a best fit of χ for the FHSC (dotted), disk (solid), and envelope (dashed), respectively. The extreme values of the enrichment given by our toy model are delimited by the blue areas. The color coding and choice of markers is the same as in Fig. 16.
