Calculate Total Field and Horizontal Derivatives

Use the Calculate Horizontal Derivative Grids option (UXDXDY GX) to compute the two horizontal derivative grids and total field magnetic grid from an existing Z-derivative grid (1VD).

Application Notes

The name of the existing first vertical derivative grid is required. This may be selected from the drop down list. The names of the total field grid and the two horizontal derivative grids are also required. If the output grid names already exist, a dialog box will appear asking if you want to overwrite them.
