Stacking (Velocity Picking)
As you pick, Insight automatically calculates a stack from your NMO-corrected gathers. You can view this like any other stack in the IL/CL, 2D Line, or 3D Views.

In the Stacking tab of the Velocity Picking window, choose a stacking mode from the drop-down list and define the positive and negative offset ranges (see Stacking).
