Projection of the magnetic field vector in the X–Z (top row), X–Y (middle row), and Y–Z (bottom row) planes intersecting the center of the 3D domain. The first and second columns show the projection of the true and the inverted magnetic field vectors, respectively. The right column shows the uncertainty of the inverted magnetic field as defined in Eq. (3), but accounting only for the two relevant components in each projection. The color of the vector arrows indicates their orientation on the projected plane.
