Extending from the peak location of an anomaly to the inflection points of the grid values along each of the 8 directions results in 8 radii. Anomaly size is defined as the 2*mediam of the 8 radii. This algorithm uses 4 successive points d1, d2, d3 and d4 in any direction. Given slopes m1 = d2-d1, m2 = d3-d2 and m3 = d4-d3, an inflection point occurs between d2 and d3 if m1>m2 and m2<m3. The location index is given as i3 - s2/(s2-s1), where i3 is the index of d3, and s1=m2-m1 and s2=m3-m2. This algorithm tends to give much smaller (and more reasonable) results than PeakSize_IMU.
