Fig. 7.

Boxplot dI values distribution at the last simulation step for the whole sample, with respect to the effects of different density classes: a) Docc ≤ 0.25; b) 0.25 < Docc ≤ 0.5; c) 0.5 < Docc ≤ 0.75; d) 0.75 < Docc ≤ 1.00 . Values are traced according to the overall mask effect. dI acceptable thresholds are defined at dI = 5% (dashed green line) and 25% (continuous red line).
