Figure 2 shows four ADCIGs obtained with wave-equation migration as described by Sava and Fomel 2003. The top two ADCIGs correspond to lateral positions directly below the left edge of the salt body (CMP positions 6744 m and 22056 m in Figure 1). Notice how the apexes of the diffracted multiples are shifted away from the zero aperture angle (e.g., the ``seagull''-looking event at about 4600 m in panel (a)). For comparison, the bottom panels in Figure 2 show two ADCIGs that do not have diffracted multiples. Figure 2c corresponds to an ADCIG below the sedimentary section (CMP 3040 m in Figure 1) and Figure 2d to and ADCIG below the salt body (CMP position 12000 m in Figure 1). In these ADCIGs all the multiples are specularly-reflected and thus have their apexes at zero aperture angle. Notice also that although the data is marine, the ADCIGs show positive and negative aperture angles. We used reciprocity to simulate negative offsets and interpolation to compute the two shortest-offset traces not present in the original data. The offset gathers were then converted to angle gathers. The purpose of having both positive and negative aperture angles is to see more clearly the position of the apexes of the diffracted multiples.
