Figure 7.

RMSE of $D_{\mathrm{a}}$, for SDE and ${\text{DDE}}_{40+20}$ acquisition protocols. This 3D plot shows the projection over f, $D_{\mathrm{a}}$, and $c_2$ of all the RMSE in the 5D grid. This projection was made by computing the square root of the quadratic mean of the errors in the remaining 2 dimensions (${\text{E}}_{proj,ijk}=\sqrt{\sum _{\ell }\sum _m{E}_{ijk\ell m}^2/(N_{\ell }{N}_m)}$). Black dots denote the actual points in the grid, linear interpolation was used to generate the color figures
