      abstract     = {Off-axis electron holography and first moment STEM are
                      sensitive to electromagnetic potentials or fields,
                      respectively. In this work, we investigate in what sense the
                      results obtained from both techniques are equivalent and
                      work out the major differences. The analysis is focused on
                      electrostatic (Coulomb) potentials at atomic spatial
                      resolution. It is shown that the probe-forming/objective
                      aperture strongly affects the reconstructed electrostatic
                      potentials and that, as a result of the different
                      illumination setups, dynamical diffraction effects show a
                      specific response with increasing specimen thickness. It is
                      shown that thermal diffuse scattering is negligible for a
                      wide range of specimen thicknesses, when evaluating the
                      first moment of diffraction patterns.},
