orthcursor should be called immediately after orthview. 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 orthview has read in a map and generated its orthographic projection, orthcursor is run to determine the position and flux of bright synchrotron sources, for example.
