Topic:
Seismic surveys have vastly different amplitude ranges.

Description:
I have two different surveys in my project, both processed by different
vendors, and their amplitude ranges are very different from one another.

How can I normalize the amplitudes of one survey to the amplitudes of the other
survey?

Solution:
Use Computation Manager > Amplitude Normalization.

1.) Computation Manager > Seismic Processing > Amplitude Normalization.
    For Normalization type, select 'Seismic Reference', the recommended 
    Reference type is 'RMS', then select the survey and class you want to
    normalize to.  OK.

2.) In the upper left corner click on the Survey button.  Select the
    survey you want the normalization to be performed on, the input class
    and assign it a new output class.  OK.

3.) Start.

Once the normalization is complete, set the posting order in Seis2DV/3DV to
display the new normalized class of data just created.

In Seis2DV/3DV

4.) Define > Display Specs 
    set the Non-existent data uses to Class Priority.  OK.

5.) Define > Class Priority 
    choose the new class from the available class list and click the top
    button to make sure that this new class is on top of the old class of
    data in the Class Priority box.  OK.
