MAP_CONVOLVE GAUSS

        [CLEAN\]MAP_CONVOLVE OutCube InCube GAUSS Major [Minor [PA]]

    Spatially smooth a data cube by the specified Gaussian OR to reach  a  given
    (circular) resolution.  Major and Minor must be in the same units as that of
    the  input  cube  axes  (i.e. Radians for astronomical images). Smoothing is
    performed by an FFT-based convolution.

    If only Major is given, and the input cube has a specified  spatial  resolu-
    tion,  MAP_CONVOLVE will attempt to provide a new spatial resolution of size
    Major. This requires that the initial major axis is smaller than Major.

    In other cases, the input cube is smoothed by specified Gaussian.
