Amplitude Scale Factor

Amplitude scaling can be applied to an individual line or to a line within a fence display.

Using the Amplitude Scaling Function

1. Right-click on the seismic line you wish to scale, and select Amplitude Scale Factor from the shortcut menu to apply amplitude scaling to the seismic.
• You could also select Tie with Diagnostics from the shortcut menu to apply phase, bulk shift, polarity, and band-pass filter adjustments in the same window as the amplitude scaling.
2. Move the slider bars up and down to apply amplitude scaling. The seismic display is updated dynamically.
• When you display a line that has an amplitude scale factor applied, the magnitude of the scale factor is displayed on the status bar in the lower left-hand corner of the WinPICS   main window. It will look like this: (Amp X 2.2), where 2.2 is the amplitude scale factor. An R will appear on the status bar when the seismic data displayed is in reverse polarity.
3. If desired, you can change the polarity of your data from the amplitude scale factor window by clicking on Normal or Reverse.
4. Click <OK> to save changes and exit.

• No changes are made to your data file. The scale factor is stored in a header file and applied to traces and picks for display, picking, plotting, and export.
