Results of FEM modeling for the area in Fig. 1 inset. a, b Observations of the EW and UD component are the same as those presented in Fig. 4a, c, respectively. c, d Synthesized distributions for the corresponding components based on the best-fit model. e Residual distribution for combinations of the free parameters, that is, the aspect ratio of the spheroidal source (abscissa: ratio of the minor axis to the major axis with typical shape schematics) and the depth (ordinate). In the left half of the chart, the aspect ratio is represented as a ratio of the horizontal axis to the vertical axis and the shape is characterized as prolate (vertically elongated), whereas in the right half of the chart, the ratio is for the horizontal axis to the vertical axis and the shape is oblate. The residuals are colored in grayscale. A red star indicates the best-fit combination of the parameters
