This tutorial shows how to create a Depth Analysis for a survey. You will learn how to view a
data cube on the 3D view tab.
This analysis calculates and displays Stack Fold. That is, fold before migration. Traces are
calculated by ray-tracing over a number of flat layers below the Survey. Traces are then binned
by their reflection point location. Station elevations are taken into account for the computation.
PP or PS reflections may be calculated
