Figure 3: Sensitivity to spatial variations in magnetization depends on the altitude of observation. We compare the relative amplitude of crustal signals as a function of spatial wavenumber (wavelength) for three different mapping altitudes. Peak sensitivity shifts to shorter wavelengths as altitude decreases (after Blakely, 1995).
