Set Join Depth for Merge

With this feature...	Do this...
Track	Select either Linear or Logarithmic track.
Left Pane	Drag the slider to move up and down the well bore to the desired overlap interval. Hover the cursor over a point in the left pane to display the depth at that location in a tooltip. Right-click this option to select Merge to merge the curves starting at the depth of the cursor and downward. Click Unmerge to remove all merging from the curves.
Right thumbnail pane	View the curve coverage and depth overlap for the curves to merge. The well bore is colored red or blue for areas over which there's coverage.
Join Depth	Type the depth at which to merge the curves.
Start with Imported Curve... \| Original Curve at entered depth	Select whether to preserve unmerged portions of either the original curve or the imported curve. As you click either of the options, the pane to the left displaying both of the curves reflects which portion of the curve will be preserved with bolding.
Curve Display Scales	Select whether to use the Min/Max range of each curve or the normalized scale range set in the alias table.
