4.4 Spot Crosshairs and Ellipses
Spot crosshairs mark the centers of spots in the Gaussian image, while spot ellipses
show their shapes. The tools for displaying spot crosshairs and ellipses are located on
the Spots menu.
Fig. 4-8. Spots menu and Edit Spot toolbar.
Note that, in a scanset, the Gaussian image must be loaded to display crosshairs and
ellipses. With the Gaussian image loaded, you can also display the crosshairs and
ellipses in the Filtered image and Raw 2-D Scan in the same scanset.
Show Crosshairs (F5, Spots menu or main toolbar) is used to display the
crosshairs in a subwindow. Use the tool or the key command in the
subwindow to toggle the display. (In a scanset, the Gaussian image must be
loaded.) To display crosshairs in all subwindows, select Show All Crosshairs
(Shift+F5, Spots menu).
