Fig. 4

2D topographic profile along the reference model line (see location in Fig. 2), showing the projected tunnel gravity data points (cyan circles) and the projected surface gravity data points (green circles). The surface gravity measurements points at their original measurement elevation are shown as red circles. Prior to comparison with synthetic values, computed at the projected locations (green circles), the gravity data points are corrected for the effects due to this projection. The procedure in explained in detail in Sect. 3
