Comparison of the updated magnetic field models described in Sect. 3.3. Each column shows one of the models. The top row shows both the coherent field amplitude in colour (on a common scale) and the projected direction shown by the arrows. The top portion of each panel shows the x-y plane at z = 0, while the bottom portion shows the x-z plane at y = 0. The bottom row shows the amplitude of a single realization of the isotropic random field component. The white cross in a black circle shows the position of the observer.
