Set Linear Scale
The Set Linear Scale command attaches a linear coordinate system to the X and Y axes of the image. The scale is equally applied to both the X axis and Y axis. To set independent linear scales, use the Set Independent Linear Scales command. Keywords that define the calibration coefficients are inserted into the image header by this command.
This command is opened from the Process > Coordinates menu.

This command applies a World Coordinate System ("WCS") calibration to the image or image set. This calibration replaces any existing WCS. However, this command creates an Undo copy so that you can use theEdit > Undo (Ctrl+Z) command to restore the previous coordinate system. To save the arcsecond calibration, save the image in the normal way.
