The PDSP model applied to SANS data obtained from three rock samples (Opalinus Clay) and three poly­di­methyl­siloxane (PDMS) polymers of volume fractions 0.128, 0.25 and 0.5 in toluene. Rock samples: (a) measured I(Q) curves after manipulation and I(Q) curves obtained from the PDSP model, (b) probability functions of the pore size distribution f(r), and (c) the error sensitivity dSSQ/dlog(IQ0) obtained after two iterations. PDMS samples: (d) the fitted PDSP model, (e) probability functions of the scatterer size distribution f(r) and (f) the error sensitivity obtained after 20 iterations.
