If this checkbox is marked, then a cartoon showing the geometry of Mars will be displayed on the results page, including the location of geologic region boundaries. If not marked, then no such cartoon will be displayed. An example is shown below, for a viewing geometry of:
       Sub-Earth Latitude = -19.6
       Sub-Earth Longitude = 200.5
       North Pole PA = 344.0
where you can see the outlines of the south pole residual ice cap, the Elysium volcanoes (upper middle), Olympus Mons and the Tharsis volcanoes (right limb), "Stealth" (setting limb), several older volcanic constructs (Orcus, Hadriaca, Appolonia, Tyrrhena paterae), and the Hellas basin (left limb).

If the antenna beam FWHM is less than the size of the planet, then a blue circle outlining the location of the half-power point is shown on the cartoon. In the example below, the diameter of the planet is 23.9 arcsec, while the beam FHWM is 10 arcsec.
