An illustration of the unsigned magnetic field strength |B| at the spherical surface r = R of the model star using an orthographic map projection. The darkest patches correspond to a maximum field strength of 500 Gauss (black on the continuous scale bar). From a snapshot at time = 695 years. The view is centered on a longitude of 100 deg. The grid indicated has a longitudinal spacing of 40 deg. and a latitudinal spacing of 20 deg. The numerical resolution of the map is 180^2 grid points.
