10-centre profile
The 10-centre profile is parallel to
the profiles 04-centre and 07-centre,
located on top of the more resistive
crustal region, further away from
the interface as the 07-centre profile
(cf. Fig. 8.4). The inversion model
is in general similar to the model
for profile 07-centre with the difference
of a significantly more conductive
region in the SW of the profile
(see Fig. A.7). This higher
conductivity (≈ 500 Ωm) is in good
agreement with the true model, denoting
the decreasing effect of the
crustal structures and their oblique
strike direction. The RMS misfit of
the 10-centre model (2.78 with a 5%
error floor for phases and 10% error
floor for apparent resistivities)
is in the same order as the misfit
for the 04-centre and 07-centre
models, wherein the misfit distribution
is similar to the latter (but with
a significantly lower misfit of TM
mode crustal data).

Fig. A.7.: Isotropic 2D inversion results for the ‘10-centre’ profile on top of the synthetic 3D model (see Figure
8.4 for station locations). An electric resistivity interface at mantle depth is located between stations synI10 and
synH10. Periods between 10 s and 100 s are related to the crust–mantle boundary; see Section 8.2.1 for a description
of the model. During the inversion the crust is kept fixed at an electric resistivity value of 100 Ωm. The misfit of the
uppermost region originates from the problematic of meeting the cell size requirements for the highest frequencies.
