Figure 8
Reconstruction of concentration profiles for two levels of acquisition noise: panels (a) and (b) very low (σk = 0.01, SNR = ), and panels (c) and (d) very high (σk = 0.5, SNR ∈ [100, 6400]). In panels (a) and (c) the profile reconstructions are plotted in blue ( ), orange ( ) and red ( ) with their respective variabilities as shaded areas. In panels (b) and (d) the a posteriori [ ] is represented in blue and the marginals in orange [ ] and red [ ]. For the noise variability ρ|Am, y0 and the noise marginal , the true values of λe have been used to emphasize the effect of uncertain attenuation lengths. |
