Fig. 4, panel (a)
Contours of the typical gravity gradient signal (E) of a buried object against depth from surface (m) and object radius (m), for a density contrast of 1.8 g cm$^{-3}$, at 10 to 600 E. The thick line is the sensor uncertainty at 10 min, the red dot the detected tunnel, and shaded boxes the ranges of four applications.
