Summary. This paper examines the effects on cylindrical slant stacks of spatially‐truncating a wide‐aperture seismic section. We demonstrate that a step discontinuity in offset coverage, usually caused by only having available a limited range of data, is responsible for the linear artifacts frequently seen in slant stacks. These we show to have slopes corresponding to the offsets of the discontinuities in the x‐t domain. We also show that the artifacts can be attenuated by applying an appropriate offset taper function to the section before slant stacking. This procedure is illustrated on some wide‐aperture seismic data shot in the Gulf of Mexico.
