            CIRCLE

        This  program  computes annular averages on an input cube to  produce an
        output  map.   Each line of the output map is the radial profile for one
        particular plane of the input cube.  The task can be used to  derive the
        radial profiles, for example in  circumstellar  envelopes.   The  radial
        pixel separation is always the X and  Y  increment.   If  the  X  and  Y
        increments  are  different,  the  averages  are  therefore  computed  on
        elliptical rings, despite the name of the task.
