The CCB main window is used to specify the inputs and parameters required for the stacking.
Inputs are:
- Surface defining the contour lines geometry
- Seismic volume to stack, post- or pre-stack.
Parameters are:
- Volume subselection: Area defining the traces that will be used for stack. This can be an entire volume, a rectangular sub-selection (possibly decimated), a table sub-selection, or a polygonal sub-selection.
- Contour Z division: start, stop and step value for the bin selection: A bin is a time/depth gate around a contour line [-step/2, +step/2]. It will be the X-axis of the 2D CCB display. Start and stop values are absolute time/depth values.
- Z range around horizon: time/depth interval used the extraction of the seismic data prior to stacking. This is a relative gate with respect to the time/depth of the contour.
Numbers must be entered in Z unit of the survey: meters, seconds or milliseconds.
Based on the selected data the traces will be collected based on the time/depth (bin) of the horizon intersection with each trace.
