UV_RADIAL

        [ADVANCED\]UV_RADIAL x0 y0 Rota Incli  [/SAMPLING QSTEP [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).  ROTA is here the position angle of axis  of  (assumed)  rota-
    tional  invariance  of  the object. Thus, when using results from UV_FIT
    one should use ROTA = PA-90, where PA is the Position Angle of the Major
    axis.

    The  result  becomes the current UV table.  The resulting UV table has a
    (u,v) coverage which is extended by rotation, so that it can be used  to
    image  the  (rotationally symmetric) 2-D radial distribution using stan-
    dard commands like UV_MAP and CLEAN.   The radial profile of the bright-
    ness  distribution can then be recovered by using any radial cut through
    this image.

    Note, however, that in a SHOW UV command with "radius" along  one  axis,
    all visibilities at different azimut are superimposed. See UV_CIRCLE for
    a different way of computing an azimutal average, more suited  for  SHOW
    UV.
