Depth Estimation Using the Tilt Angle of Gravity Field due to the Semi-Infinite Vertical Cylindrical Source

Figure 3

(a) Gravity anomaly of Figure 2(a) contaminated with random noise with standard deviation of 0.0001 mGal and average 0.0005 mGal. (b) Tilt angle of data in the Figure 2(a). (c) Depth estimates from TDD method. The correct depth value (20 m) is drawn as a horizontal green dotted line. The vertical pink line shows the horizontal location of the source center. (d) Solutions from TDD and Euler deconvolution (using a structural index of 1 and a window size of 7 points) methods represented by red + and blue × symbols, respectively.
