distribution for the entire image. Select the command from the menu or
toolbar, and click on the image.
Plot Cross-section
To display a cross-sectional intensity trace centered on a point on the

Ctrl+T key command, and click or drag on the image. The trace will be
displayed, and will be continuously updated as you move your cursor
over the image. The intensity (in ODs or counts) at the cursor point is listed, as is the
maximum intensity along the lines of the cross-section.
