Figure 2From: A new leveling method without the direct use of crossover data and its application in marine magnetic surveys: weighted spatial averaging and temporal filtering Weight function W ( d ) for various values of weight distance d 0 . The function decreases rapidly with d for d > d 0. Parameter d 1 (=15 km) is the distance limit of the weight function. Note the logarithmic scale used for the y-axis.Back to article page
