Suggested change

"Numerical artefacts due to the discretization of topography decay sufficiently when receivers are roughly two cell dimensions away from the nearest edge or corner of a mesh cell in the air/earth boundary. For example, if the lowest drape height in given airborne survey is 60 m, a prudent cell size would be in the range of ~30 m. Another rule of thumb is that the cell size should be smaller than half the smallest data spacing. This is especially important for electrical methods where the electric field may be discontinuous and numerical artefacts may arise if the cells are not small enough to capture rapid changes in the field. For example, a 40m dipole direct-current survey would suggest a cell size around ~20m.\n",
