From: A new leveling method without the direct use of crossover data and its application in marine magnetic surveys: weighted spatial averaging and temporal filtering

Figure 8

Magnetic anomaly maps from the Kaiko project before and after leveling correction. False anomalies along some of the track lines in the map before correction (A) disappear after leveling correction using a filtering width of 6 h and a weight distance of 0.5 km (B). Some improvements in anomaly patterns are also recognized in the box at the southwest end. Contours are at 20 nT intervals; thicker contours are at 100 nT intervals.
