    Compute a UV table containing the radial distribution of the azimutal  aver-
    age  of  the visibilities after deprojection for inclination and orientation
    (Incli, Rota, in Degrees) around a specified  center  (x0,y0   in  Radians).
    ROTA  is  here the position angle of axis of (assumed) rotational 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  standard  commands
    like  UV_MAP  and CLEAN.   The radial profile of the brightness 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 dif-
    ferent way of computing an azimutal average, more suited for SHOW UV.
