Seismic Datum: The seismic datum for the project. This value is for your information and can't be changed from this location.

Depths referenced from datum: Use this option when the depths should be subsea.

Apply residual adjustment: Apply a residual to the output grid. This is used to make your depth maps tie more closely to the top depth values.

Cell Size: Specify the cell size, in map units, for the output grids. Entering a small value will result in longer gridding times. You can also change this value from the Standard Toolbar.

Velocity Scale Factor: Specify the number of grid cells to combine into a single velocity value. Use this to speed up gridding and smooth the velocity grid. The resulting depth grid will more closely reflect the time grid.

Output Depths Units: Select the depth units for the output grid. This will default to the depth units of the project.
