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. Also see the
Calibrate Linear Scale command to interactively
set a linear scale based on a mouse-drawn line.

The Set Linear Scale command opens from
the Image Window > Coordinates menu and button on the Main Toolbar. The "immediate" form, shown first,
opens when an image or image set is displayed in the top-most
window. The general form can be used to select source images from
folders, windows, or by matching templates.

This command applies a
World Coordinate System ("WCS") calibration to
the image or
image set to replace any existing WCS. The new
calibration may be reversed using
Edit > Undo (Ctrl+Z) to restore the previous coordinate
system. To permanently save the arcsecond calibration to the image
file, save the image in the normal way.
