cartcursor should be called immediately after cartview. It gives the longitude, latitude, map value and pixel number corresponding to the cursor position in the window containing the map generated by orthview. For more details, or in case of problems under Mac OS X, see mollcursor.
After cartview has read in a map and generated its cartesian projection, cartcursor is run to determine the position and flux of bright synchrotron sources, for example.
