        Compute  a  UV  table containing the radial distribution of the azimutal
        average of the visibilities after deprojection for inclination and  ori-
        entation  (Incli, Rota, in Degrees) around a specified center (x0,y0  in
        Radians). All arguments default to 0.  ROTA is here the  position  angle
        of axis of (assumed) rotational invariance of the object. Thus, when us-
        ing results from UV_FIT one should use ROTA = PA-90, where PA is the Po-
        sition Angle of the Major axis.

        The  resulting UV table have visibilities only with V values equal to 0,
        so that the U values contain the radial distance in the UV plane.   This
        is  convenient  to display the azimutal average of the visibilities as a
        function of UV distance, but cannot be used for further imaging.

        See UV_RADIAL if you want to image the circular average of  the  bright-
        ness distribution.
