Figure 1: Open FK tool box.

Open vertical component of signal recorded at 2D array receivers in the graphic viewer and click on menu "Tool/High resolution F-K" (Figure 2), or alternatively click on the "FK" icon in the tool bar (). Then the FK tool box, which has the same appearance as the FK tool box, appears on the screen (Figure 3).

Figure 2: Open HRFK tool box.

despite the fact that the computation of the FK and the HRFk method are different (see ), the input processing parameters are the same. Therefore, the appearance of both tool boxs and the way of set up input parameters are the same for both method.
