SAOimage World Coordinate System
Cursor Commands

If WCS information is present in the FITS image header, SAOimage versions from 1.12 track world coordinate systems as well as pixel coordinates within the image. In versions 1.17 and after, spatial WCS information is extracted from IRAF .imh (OIF) images as well. Several single character keyboard commands have been added:

In SAOimage 1.14 through 1.17, the b, j, and g keys print the coordinates to standard output. In later versions, they only change the tracking window, and the c key prints whatever is in the tracking window.
