Figure 4. Polar sterographic projection from 55oS to the south pole of Mars. (Left) The radial (vertical) component of the magnetic field is illustrated using the same color scale as Fig. 3. Coverage of this region is sparse and does not allow binning, sorting, and smoothing as done for Fig. 1. Superposition of magnetic field data acquired from largely nonoverlapping orbits is shown instead. Note the change in intensity scale with respect to Fig. 1. The polar sterographic projection provides a more realistic spatial illustration of the Terra Sirenum crustal sources, where linearly structured magnetic field sources are found. (Right) Mars south polar region topographic image corresponding to the left panel above included for reference (16).
