Fig. 10.

Linear fit of ${\text{Impact factor}}_{HS}$ versus the sum of ${\text{Impact factor}}_{HOAs}$ and ${\text{Impact factor}}_{Scatter}$. Each point represent an average value across subjects for a spatial frequency. Blue circles stand for results obtained with Filter S0.5; green triangles stand for results obtained with Filter S1; magenta diamonds stand for results obtained with Filter S2. The solid line represent the fitting line; the dotted line stand for the line y = x.
