The WCS Keywords command finds all the World Coordinate System ("WCS") related keywords in an image header and lists them into a Text window. If the Image window contains an image set, the current image or the image set may be listed according to the status of the Process Image Set flag, or button.
This command is available in two menus: the Edit > Image Header menu and the View > Coordinates menu.
The example below lists WCS keywords from a fully calibrated image header. Note that the ".txt" extension is automatically appended to the window title after the contents are saved to a file.
