Figure F16. Cross-correlation results for the tie, Site U1421. Before matching (left), the maximum cross-correlation within 5 traces of the site, nearest Trace 411 on Line GOA 2503, was 0.417 with Trace 414 at –1 ms lag when correlating the 980–1650 ms window. At the site trace, we calculate the cross-correlation with the synthetic at 0 ms lag to be 0.365, which was also the maximum cross-correlation value in the trace window at any lag. After matching (right), the maximum cross-correlation, 0.500, occurred at Trace 413 with 0 ms lag. At Trace 411, the nearest to the site, the zero lag cross-correlation was 0.413 and the trace maximum cross-correlation, 0.448, occurred at 1 ms lag. White asterisk = trace of maximum cross-correlation.
