Select the Horizon to Flatten on:Select the horizon you want to use to flatten your display. To help you make your horizon selection, you can left click on the column header to sort any of the columns, you can apply a filter (), or you can type a search string into the search bar to limit the list based on Name, Type,or Ownerinformation.

Datum Time:Specify a reference datum time for the flattened horizon.

Blank Traces Without Picks:If this is turned on, traces located where there is no associated horizon pick will have the value 0. If it is not set, traces without picks will be referenced against the datum time. For example, if there is no horizon pick at a given trace, and the datum time is 600, trace values will be extracted above and below the 600 ms point of the data.

Apply parameters to subsequent views: If this is turned on, your choices will be saved until the next time you open the dialog.

Flatten:Display the graph with the flattened horizon.

Unflatten:Display the graph with the normal horizon.
