 Beware that the reference solution is not exact, only quasi-exact (i.e., the formulation uses an approximation, and some integrals are computed numerically) therefore some small discrepancies can be noticed.
 
-More importantly, in the example provided, "tau" relaxation times for attenuation memory variables are recomputed using approximate quality factor targets of Qkappa approximately equal to 27 and Qmu / Qs approximately equal to 20, read (roughly) from Figure 1 page 604 of the article of Carcione et al. (1988). This will NOT lead to the exact same "tau" values as in Table 1 of Carcione et al. (1988). Thus, in order to perform a far more precise comparison to the analytical solution, which is computed using the "tau" values from Table 1 of Carcione et al. (1988), in file "src/specfem2D/attenuation_model.f90" you should impose this instead for this test (only):
