Calculate the curvature on a grid

Follow these steps:

1. Select one of your project's grids from the Grid Name list.
2. Select an Attribute (time or amplitude) to use for the calculation.

3. Select the curvature Type.
4. In the Apperture box, type the fraction of the scanning window you want to apply the curve to. For example, type 2 if you want to use half of the scanning window.
5. Type the curvature Scale.
6. Type a Grid Name for the output, or select an existing grid name from the list.
7. If you select an existing grid, WinPICS will overwrite the grid's amplitude field.
7. Click <OK>. The progress status bar displays the status of the calculation.
