Abstract
Time-coherency traces generated during velocity analysis are displayed in panels where each panel contains traces representing a single selected trial stacking velocity function and a plurality of common midpoint locations along a seismic line of exploration. Points selected from the panels, optimally by comparison with stacked sections, are used to generate a time velocity funtion for stacking, NMO correction, interval velocity determination, or other uses.
