UV_CIRCLE

        [ADVANCED\]UV_CIRCLE [x0 y0 Rota Incli]
      [/SAMPLING QSTEP [Unit [QMIN QMAX]]] [/ZERO [Flux]]

    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.
