Select a model(s) to modify (SHIFT+CLICK or CTRL+CLICK for multiple selection), then click either New or Duplicate.

Type a more descriptive name for the model.

Select from the following:

• Zero offset
• Multi offset
• Derived based on a mathematical operation performed on two other models in the current synthetic.

Select the mathematical transformation used to explain the data.

Type the display amplitude of the trace data.

Select the source curve and method to use when creating the AVO logs. Click Create AVO Log suite to create numerous types of logs to use in AVO analysis.

Select whether to display simulated first order multiples alongside primary reflections, or to just display multiples and not the primary reflection. First order multiples are the first reflection of a primary reflection.

Type the maximum percent for the reflection coefficient below which multiples are not shown. GeoSyn calculates the maximum reflection coefficient in the model, uses a percentage of that, and ignores all reflection coefficients less than that.

Type a value in milliseconds for the automatic gain control.

Select the Apply check box and then click Edit to display the Noise Parameters dialog box, where you apply noise type.

Specify the following:

• Traces/in - The number of traces to display per inch in the main window.
• Traces/grp - The number of traces to display in a group and whether to display both positive and negative groups.
• Spacing - The amount of space between groups of traces.
• Color - A line style and color and then click Edit to display the Edit Color Palette dialog box.
• Underlay link - Shows whether the current trace displays highlights from a crossplot using the Crossplot Viewer: Color Mapping tab.
• Quick change - Apply multiple changes simultaneously. These options are groups of individual options that also appear in the Attribute drop down list above.
• Font - Click Edit and specify a font for model labels.
