SPECTRAL_CLEAN WAVE

        [BUNDLES\]SPECTRAL_CLEAN WAVE

    Clean a Wavelet Transform along the spectral axis of  the  DIRTY  cube,  and
    transform back the Clean components to retrieve the per-channel Clean compo-
    nents. The final Clean image is produced using UV_RESTORE.

    The noise level is not the same for the wavelet components of the data cube:
    this  is  taken into account by the method to Clean each wavelet image plane
    to its proper noise level.

    Apart for the time required by the Wavelet transform, the method has a  com-
    parable speed to a standard Clean.
