Wide tow data with four streamers and two alternating shots. The nominal cross-line spacing is 25 meters, however, cross line dipping reflectors and diffractions require denser sampling. Therefor the data were processed with 12.5 by 12.5 meter bins. For AVO analysis, the data were processed in offset bands. Here we show one offset band of 1000 to 1500 meters. Cable feathering in opposite directions between adjacent passes create a coverage gap.
In addition to that, to simulate reduced in-fill, the data of one streamer were dropped.
