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.
