  1. The mean electric field values for \( \left|\overrightarrow{\mathrm{E}}\right| \) and E within the target region. For each location the value for the standard coil orientation and the optimized coil orientation are given. The optimized values are determined for both outcome measures (\( \left|\overrightarrow{\mathrm{E}}\right| \) and E) individually. The cortical target location coding can be found in Table 1.
