Session 3.2 ___ GNGTS 2023 Fig. 3 – Inverted section CMD-Explorer (a), inverted section Dualem – 642 (b); CMD-Explorer section calibrated by ERT (c); Dualem-642 section calibrated by ERT (c). Interpreted EM section in d). The root mean square error (RMSE) is 0.8 Ohm.m, 0.8 Ohm.m, 0.4 Ohm.m, and 0.2 Ohm.m, from a) to d), respectively. Tab. 2 shows the absolute errors between measured and calculated data from the ERT model for DUALEM and CMD-Explorer, with an improvement of about 103% and about 123%, respectively.
