Figure 3From: A new leveling method without the direct use of crossover data and its application in marine magnetic surveys: weighted spatial averaging and temporal filtering Function T ( t ) and Gaussian filtering function G ( t ). (A) Functions T(t) and (B) G(t) for the filtering widths 2t 0(=2t 1) of 3, 6, and 12 h. Function G(t) > 0 but T(t) = 0 for t < t 0 (=t 1).Back to article page
