Figure 2: Magnetic field map of Terra Meridiani, as in Figure 1, but centered on the zero meridian. Dashed lines indicate parallel great faults drawn as small circles about a common rotation axis (+) intersecting the sphere northeast of Hellas (23° S, 83.5° E). The white line marks an axis of symmetry with respect to the magnetic field.
