Focus:
Use Focus during Playback Mode to estimate a dielectric value. This option is only available when displaying
the X- or Y-slices. This turns on the Migration and Hilbert Filters from the Signal Process menu.
1
Turn Focus On and adjust the percent of coverage. You can either Focus 24%, 50%, 75%, or 100% of the X- or
Y-slices.
2
Move the Dielectric slider to the right of the data up or down to adjust the Dielectric Constant. You will see the
value change at the very top of the screen.
3
Obtaining a better Dielectric Constant is done by moving the vertical slider until the hyperbolic reflections become
dots or vertical bars. See Appendix C for more information.
4
The new Dielectric Constant is automatically applied to all of the profiles in the 3D grid.
Stop Playback:
Return to the Playback Setup Screen.
Set Depth:
Input a known depth to the data. This will update the dielectric value accordingly.
1
Place the stylus pen on the screen.
2
Move the pen around and place the horizontal line at the known depth.
3
Tap the Set Depth Icon.
4
Enter and accept the known depth.
Focus On:
Turns on Focus Mode to adjust the Dielectric Constant and
get more accurate depth estimates.
Pause:
Pauses playback.
