Variation of the reconstructed TGSD (a) Mdϕ and (b) σϕ vs. the input TGSDs (no fitting); (c) x0 and (d) l of the Rosin-Rammler fitting vs. the input TSGD. The black lines mark 1:1 ratio between the reconstructed and the deposit parameters, dotted lines enclose reconstructed TGSDs parameters with values within 30% (almost 1 ϕ) of the corresponding deposit ones. Symbols: red full circles = CW sampling; blue full circles = WS sampling; pink open circles = DW sampling with 10 points; black open circles = DW sampling with 20 points; green open circles = DC sampling.
